Description

(3R,4S)-3-히드록시-4-페닐아제티딘-2-온의 제조방법과 그 중간체Method for preparing (3R, 4S) -3-hydroxy-4-phenylazetidin-2-one and intermediates thereof

본 발명은 하기 일반식(1)로 표시되는 (3R,4S)-3-히드록시-4-페닐아제티딘-2-온의 신규한 제조방법 및 그 중간체들에 관한 것이다.The present invention relates to a novel process for preparing (3R, 4S) -3-hydroxy-4-phenylazetidin-2-one represented by the following general formula (1) and intermediates thereof.

상기 일반식(1)의 화합물은 하기 일반식(2)로 표시되는 탁산계 항암제의 측쇄 치환기인 일반식(3)의 N-치환된 (2R,3S)-3-페닐아이소세린의 전구체이므로 일반식(2)의 화합물의 합성공정에 필요한 중간체이다.Since the compound of Formula (1) is a precursor of N-substituted (2R, 3S) -3-phenylisoserine of Formula (3), which is a side chain substituent of the taxane-based anticancer agent represented by the following Formula (2), It is an intermediate required for the synthesis | combining process of the compound of Formula (2).

일반식(2)로 표시되는 탁산계 화합물은 항암제로 알려져 있는 바, R이 페닐기이고 R'이 아세틸기인 경우에는 파클리탁셀(Paclitaxel) 또는 탁솔(TaXOl)이라 부르며, R이 3차 부톡사이드(t-BuO)기이고, R'이 수소원자이면 도세탁셀(Docetaxel) 또는 탁소테르(taxotere)이라고 부른다.The taxane-based compound represented by Formula (2) is known as an anticancer agent. When R is a phenyl group and R 'is an acetyl group, it is called paclitaxel or Taxol (TaXOl), and R is a tert-butoxide (t- BuO) group and when R 'is a hydrogen atom, it is called docetaxel or taxotere.

(식 중, R은 페닐기 또는 t-BuO기임)(Wherein R is a phenyl group or a t-BuO group)

난소암이나 유방암에 탁월한 효능을 나타내는 일반식(2)로 표시되는 탁산계 중에서 항암제로 유용한 파클리탁셀은 주목나무 (Pacific yew tree)의 껍질로 부터 얻어진다. 그러나 추출물의 수율이 매우 낮아 대량으로 공급할 수 없고 더욱이 대량으로 생산할때에는 심각한 자연훼손이 예상된다. 반면 유럽산 주목나무(European yew tree)의 잎이나 잔가지로부터는 파클리탁셀의 주고리의 골격과 기능기를 모두 가진 일반식 (4)로 표시되는 10-디아세틸-박카틴-Ⅲ (10-deacetyl-baccatin-Ⅲ)가 추출되는데 이는 추출물의 수율이 비교적 높을 뿐만 아니라 재생가능한 잎이나 잔가지를 원료로 한다는 장점을 가지고 있다. 최근 새로 개발된 항암제 도세탁셀은 일반식(4)로 표시되는 10-디아세틸-박카틴-Ⅲ으로 부터 순수한 합성경로를 통해 제조된다.Among the taxanes represented by the general formula (2) showing excellent efficacy on ovarian cancer and breast cancer, paclitaxel, which is useful as an anticancer agent, is obtained from the bark of the Pacific yew tree. However, the yield of the extract is so low that it cannot be supplied in large quantities, and moreover, serious natural damage is expected when producing in large quantities. On the other hand, from the leaves or twigs of the European yew tree, 10-deacetyl-baccatin-III represented by the general formula (4) having both the skeleton and functional groups of the ring of paclitaxel. ) Is extracted, which has the advantage that the yield of the extract is relatively high, as well as renewable leaves or twigs as raw materials. The newly developed anticancer agent docetaxel is prepared through a pure synthetic route from 10-diacetyl-baccatin-III represented by the general formula (4).

따라서, 현재까지는 일반식(4)로 표시되는 10-디아세틸-박카틴-Ⅲ과 일반식(3)의 N-치환된 (2R,3S)-3-페닐아이소세린을 출발물질로 하는 파클리탁셀, 도세탁셀의 반합성 공정이 가장 실용적이며 경제적이라고 알려져 있다.Therefore, paclitaxel starting from 10-diacetyl-baccatin-III represented by the general formula (4) and N-substituted (2R, 3S) -3-phenylisoserine of the general formula (3), The semisynthetic process of docetaxel is known to be the most practical and economical.

그러나, 일반식(4)로 표시되는 10-디아세틸-박카틴-Ⅲ을 원료로 하는 일반식 (2)의 탁산계 항암제의 반합성 공정에 관한 공지의 문헌[Eur. Pat. Appl. 1990; EP 400,971; J. Org. Chem., 56. 1681,(1991) ; Tetrahedron, 48, 6985, (1992) ; Tetrahedron Lett., 32, 3151 (1991) ; Synlett., 1992 761; J. Am. Chem. Soc., 110, 5917 (1988)]에 따르면, 일반식 (1)의 (3R,4S)-3-히드록시-4-페닐아제티딘-2-온과 일반식(4)의 10-디아세틸-박카틴-Ⅲ 화합물을 출발물질로 하여 일반식 (2)의 화합물을 제조하는 반합성공정이, 일반식 (3)의 N-벤조일 (2R,3S)-3-페닐아이소세린과 일반식 (4)의 10-디아세틸-박카틴-Ⅲ 화합물을 출발물질로하여 제조되는 반합성공정에 비해 생성물의 수득률과 광학적 순도가 월등히 높은 경제적인 방법임이 공지되어 있다. 일반식(1)의 (3R,4S)-3-히드록시-4-페닐아제티딘-2-온을 일반식(3)의 N-치환된 (2R,3S)-3-페닐아이소세린 대신 사용할 경우 일반식(4)의 10-디아세틸-박카틴-Ⅲ과의 결합수율이 높을 뿐만 아니라 일반식(2) 화합물의 일부 탄소 위치(C-2'위치)의 부분이성질화(epimerization)반응이 거의 일어나지 않아 생성물의 광학적 순도가 크게 향상되기 때문이다.However, a well-known document relating to the semisynthetic step of the taxane-based anticancer agent of the general formula (2) using 10-diacetyl-baccatin-III represented by the general formula (4) [Eur. Pat. Appl. 1990; EP 400,971; J. Org. Chem., 56. 1681, (1991); Tetrahedron, 48, 6985, (1992); Tetrahedron Lett., 32, 3151 (1991); Synlett., 1992 761; J. Am. Chem. Soc., 110, 5917 (1988)], (3R, 4S) -3-hydroxy-4-phenylazetidin-2-one of formula (1) and 10-diacetyl of formula (4) A semisynthetic step for preparing the compound of formula (2) using the baccatin-III compound as a starting material is obtained by using N-benzoyl (2R, 3S) -3-phenylisoserine of formula (3) and formula (4). It is known that the yield and the optical purity of the product are much higher than those of the semi-synthesis process prepared using the 10-diacetyl-baccatin-III compound of) as a starting material. (3R, 4S) -3-hydroxy-4-phenylazetidin-2-one of formula (1) may be used in place of N-substituted (2R, 3S) -3-phenylisoserine of formula (3) In case of not only high yield of binding to 10-diacetyl-baccatin-III of general formula (4) but also partial isomerization reaction of some carbon position (C-2 'position) of compound of general formula (2) This rarely occurs because the optical purity of the product is greatly improved.

다만, 현재까지는 일반식(1)로 표시되는 (3R,4S)-3-히드록시-4-페닐아제티딘-2-온의 제조가 용이하지 않았으므로 일반식(1)의 화합물 대신 일반식(3)의 화합물이 사용되어 왔다.However, until now, the preparation of (3R, 4S) -3-hydroxy-4-phenylazetidin-2-one represented by the general formula (1) was not easy, and instead of the compound of the general formula (1) The compound of 3) has been used.

실제로, 일반식(1)로 표시되는 (3R,4S)-3-히드록시-4-페닐아제티딘-2-온의 유용성으로 인하여 이의 제조방법에 관한 많은 연구가 진행되어 왔는데 몇가지 예를 소개하면 다음과 같다.In fact, due to the usefulness of (3R, 4S) -3-hydroxy-4-phenylazetidin-2-one represented by the general formula (1), a lot of research has been conducted on the preparation method thereof. As follows.

유럽 특허 출원 제 EP 400,971호에서는 파라-메톡시페닐벤즈알디민과 아세톡시에세틸클로라이드를 염기 존재하에 2,2-고리화 첨가반응시켜 라세미 혼합물의 시스-파라-메톡시페닐-3-아세톡시-4-페닐아제티딘-2-온을 제조하고 이로부터 일반식(1)의 (3R,4S)-3-히드록시-4-페닐아제티딘-2-온을 라세미 혼합물로 제조한 후 이들을 광학적으로 순수한 메톡시-2-(트리플루오르메틸)-페닐아세틸클로라이드를 이용하여 광학분할하는 방법을 사용하였다.European Patent Application EP 400,971 discloses cis-para-methoxyphenyl-3-acetase of racemic mixtures by the addition of para-methoxyphenylbenzaldehyde and acetoxyethylchloride in the presence of a base. Toxoxy-4-phenylazetidin-2-one was prepared from which (3R, 4S) -3-hydroxy-4-phenylazetidin-2-one of formula (1) was prepared as a racemic mixture. They were used to optically divide using optically pure methoxy-2- (trifluoromethyl) -phenylacetylchloride.

한편, 또다른 공지방법[J. Org. Chem., 56, 1681 (1991); Tetrahedron, 48, 6985 (1992); Tetrahedron Lett., 32, 3151 (1991)]에서는 N-트리메틸실릴 벤즈알디민과 키랄보조제가 결합되어있는 키랄에놀레이트화합물을 -78℃에서 2,2'-고리화첨가반응(2,2'-cycloaddition)시켜 일반식(1)의 (3R,4S)-3-히드록시-4-페닐아제티딘-2-온을 제조하였다.Meanwhile, another known method [J. Org. Chem., 56, 1681 (1991); Tetrahedron, 48, 6985 (1992); Tetrahedron Lett., 32, 3151 (1991)], describes the reaction of chiral enolate compounds with N-trimethylsilyl benzaldimine and chiral adjuvant at 2,2'-cyclic addition reaction (2,2 ') at -78 ° C. -(cycloaddition) to prepare (3R, 4S) -3-hydroxy-4-phenylazetidin-2-one of the general formula (1).

그러나 상기의 첫번째 방법은 제조공정이 복잡하고, 수율이 50%이상이 될 수 없으며, 수차례의 정제과정이 필요한 비효율적인 광학 분할 방법을 사용하였고, 두번째 방법은 대기중 극미량의 수분에도 극도로 예민하여 가수분해되는 반응물질들을 사용하며 또한 산업적인 면에서 반응온도가 지나치게 극저온이고, 고가인 키랄보조제를 1 당량이상 사용해야 한다는 문제점이 있었다. 따라서 이들 공지의 방법들은 실험실적인 규모로는 유용할지 모르나 일반식(1)의 (3R,4S)-3-히드록시-4-페닐아제티딘-2-온의 산업적인 규모로 생산하기에는 많은 어려움이 있었다.However, the first method uses an inefficient optical splitting method, which is complicated in the manufacturing process, the yield cannot be more than 50%, and requires several purification processes. The second method is extremely sensitive to the minute moisture in the atmosphere. There is a problem in that the reaction temperature is used to hydrolyze, and in the industrial aspect, the reaction temperature is too cryogenic and an expensive chiral adjuvant must be used in one equivalent or more. Thus, these known methods may be useful on a laboratory scale, but there are many difficulties to produce on an industrial scale of (3R, 4S) -3-hydroxy-4-phenylazetidin-2-one of formula (1). there was.

따라서, 본발명은 상술한 바와 같은 종래 기술의 문제점을 해결하고, 산업적으로 적합함은 물론 높은 수득률과 함께 광학적으로 순수한 일반식(1)의 (3R,4S)-3-히드록시-4-페닐아제티딘-2-온의 신규하고 진보된 제조방법을 제공하고자 한다.Accordingly, the present invention solves the problems of the prior art as described above, and is (3R, 4S) -3-hydroxy-4-phenyl of formula (1) which is optically pure with industrial yield as well as high yield. It is intended to provide a new and advanced process for preparing azetidin-2-ones.
