Definitions
- the invention relates to the subject matter characterized in the claims, that is new intermediates and processes for their preparation and use.
- the process for the preparation of new intermediates is based on inexpensive starting materials, provides the intermediates in high enantiomeric purities, in high chemical purity, in good yields and allows large-scale production.
- Epothilones are 16-membered macrolide rings isolated from cultures of the myxobacterium Sorangium cellosum and are representative of a class of promising antitumor agents that have been tested as effective against a variety of cancer lineages.
- An overview of the syntheses is given by J. Mulzer et al. in J. Org. Chem. 2000, 65, 7456-7467.
- Sg1 and Sg2 are protecting groups well known to those skilled in the art, e.g. the TBDMS group.
- a possible production of the A building block is described, for example, in WO00 / 58254 (University of Wisconsin). Therein a synthesis of ⁇ -keto esters is disclosed, which can be converted in multi-stage sequences in the building block A. The chirality is introduced by an asymmetric hydrogenation of a Noyori ⁇ -ketoester:
- the conversion of the ester group into a ketone can only be achieved by means of a multistage sequence.
- the ester group (C-5 atom) is reduced to the alcohol, the oxidation to the aldehyde takes place, the Grignard addition of an alkyl radical with an alkylmagnesium or alkyllithium compound provides a secondary alcohol, which is subsequently oxidized.
- a total of 6 steps are required.
- the direct reaction of an ester is not selective because the intermediately produced product continues to react.
- the following scheme shows the entire synthetic pathway:
- J. Org. Chem. 2000, 65, 7456-7467 further describes an asymmetric synthesis of a ß-ketoester, wherein a variant is carried out in asymmetric form as aldol reaction.
- the catalyst used in this method is D-Ts-valine, which can be prepared from the expensive amino acid D-valine. This method returns an ee value of 90%.
- RE Taylor, Y. Chen, Org. Lett. (2001), 3 (14), 2221-2224 describes an asymmetric aldol reaction in which the yield is 71%.
- the present invention has the object to be able to produce a universally usable starting intermediate of the general formula I and the optically pure antipodes of the general formulas Ia, Ib.
- R1, R2 can be identical or different and independently of one another for an alcohol protecting group familiar to the person skilled in the art, for example benzyl, 4-methoxybenzyl, 3,4-dimethoxybenzyl, THP, TBDMS, TMS, TES, TIP, TBDPS, MEM, MOM, allyl, trityl,
- the compounds according to the invention are stable on storage and are for the most part crystalline solids and can be purified by crystallization. In this way, high chemical and optical yields (e.e.> 98%) can be achieved.
- R 1 is a protective group as defined above, by cleavage of the protecting group R 1 according to the methods known to those skilled in the deprotection of alcohols produce (PJ Kocienski in "Protecting Groups", Georg Thieme Verlag Stuttgart , New York 1994 / Houben Weyl, 4 th Ed Vol Vl / 1b P. 737, Thieme Stuttgart 1984)
- Y and R1 are as defined above and L is a silyl protecting group, e.g. TBDMS, TMS, TES, TIP, TBDPS is prepared in a manner known per se to those skilled in the art by the techniques of aldol condensation.
- TBDMS silyl protecting group

Pirs, Chirabase, Pure and Applied Chemistry, 1993, 65, 235-244), especially by SMB technique: (A. Seidel-Morgenstern et al., Chromat A 1998, 827/2, 175-191).
- R3 is a C1-C6 alkyl group or an allyl-phenyl, or benzyl group, prepared according to methods known in the art esterification. and saponified by enzymatic or microbiological methods enantioselectively.
- the resulting alcohol differs significantly in its Rf value from the ester used, so that both can be conveniently separated from each other, e.g. by
