The present invention relates to a method for producing unsaturated alcohols that can be rearranged into compounds having a terpene skeleton or a skeleton similar to a terpene. When 1,2-epoxy-3-butene is reacted with an organic compound of magnesium or lithium RM [R represents a methyl group, M represents MgX (X represents Cl, Br or I) or Li], R
It is known that hydroxybutene can be obtained in which hydroxybutene is introduced into the 2- and 4-positions [RJ
Anderson, J.Amer.Chem.Soc., 92 , 4978 (1970)
and RWHerr and CRJohnson, J. Amer.
Chem.Soc., 92 , 4979 (1970)]. The reaction is shown by the following formula. In this reaction, the isoform 1-hydroxy-
2-methyl-3-butene and normal type 1-hydroxy-2-pentene are produced simultaneously in a relatively wide range of ratios, and it is not possible to produce either one with good selectivity. In addition to the above reactions, reactions between unsaturated epoxy compounds and vinyl copper and vinyl lithium reagents are also known (C. Cahiez et al.,
Synthesis, 1978 , 528), the same tendency as above is observed in these reactions. In the process of detailed study of the above reaction, we found that when an organotin compound having an allylic hydrocarbon group is used instead of an organic compound of magnesium or lithium in the presence of a certain Lewis acid, the 2-position The allyl type hydrocarbon group can be introduced with high selectivity, and the obtained unsaturated alcohol can be converted into a compound having a terpene skeleton or a skeleton similar to a terpene by thermal rearrangement (Cope rearrangement). This finding was obtained. The present invention has been achieved based on such knowledge, and according to the present invention, the general formula (In the formula, R 1 and R 4 each independently represent a hydrogen atom or a lower alkyl group, or together represent a lower alkylene group, and R 2 and
R 3 each independently represents a hydrogen atom or a lower alkyl group) and the general formula [In the formula, R 5 is a hydrogen atom, an alkyl group, an alkenyl group, or a formula

IRにより行つた。結果をまとめて表1に示す。[Formula] represents a hydrocarbon group in which n is an integer of 2 or more, such as geranylmethyl, farnesylmethyl, geranylgeranylmethyl, solanesylmethyl, decaprenylmethyl, and the like. In the above formula, n is 12
The following integers are preferable. R6 and R7
is optionally selected from alkyl groups, alkenyl groups, and hydrogen atoms as mentioned for R 5 . In the present invention, the reaction between the unsaturated epoxy compound and the organotin compound is carried out by bringing the two into contact in the presence of boron trifluoride, boron trifluoride etherate (e.g. diethyl etherate) or aluminum chloride as a catalyst. However, from the viewpoint of reaction selectivity, the reaction temperature is preferably a relatively low temperature such as 0 to -80°C. Although the reaction solvent is not essential, it is preferable to use one that does not participate in the reaction from the viewpoint of selectivity; for example, methylene chloride, carbon tetrachloride, chloroform, etc. can be used. The ratio of the unsaturated epoxy compound represented by the general formula () to the organic tin compound represented by the general formula () is not strictly limited, but a range of 0.2 to 5 moles of the latter per 1 mole of the former is appropriate. The order of charging the reactants and catalysts can be arbitrarily selected, but for example, in a reaction using boron trifluoride etherate as a catalyst, an unsaturated epoxy compound represented by the general formula () and an organic tin represented by the general formula () are used. The yield is generally high when boron trifluoride etherate is added dropwise to a mixed solution with the compound. The organotin compound represented by the general formula () used in the present invention is, for example, the general formula () as shown below.
It can be prepared by reacting an organic halide represented by the formula () with a lithium tin compound represented by the general formula (). Note that the lithium tin compound represented by the general formula () can be obtained, for example, by the following reaction (i), (ii), or (iii). (i) HSnR 8 R 9 R 10 +C 4 H 9 Li→LiSnR 8 R 9 R 10 (ii) (R 8 R 9 R 10 Sn) 2 +C 4 H 9 Li→LiSnR 8 R 9 R 10 (iii) R 8 R 9 R 10 SnX + Li → LiSnR 8 R 9 R 10 Alternatively, as shown below, by reacting an organomagnesium halide represented by the general formula () with an organotin halide represented by the general formula (). An organotin compound represented by the general formula () can be prepared. In each of the above formulas, R 5 , R 6 , R 7 , R 8 , R 9 and R 10 are as defined above, and X represents a halogen atom. Further, the unsaturated epoxy compound represented by the general formula () used in the present invention is prepared, for example, by the following reaction. (1) Reaction of diene and peracid (In the formula, R represents a hydrocarbon group) [For example, JK Crandall et al., J.Org.
Chem., 33 , 423 (1968) and N. Heap et
al., J.Chem.Soc., (B), 164 (1966)] (2) Reaction of sulfur and α,β-unsaturated aldehydes [For example, EJCorey et al., J.Amer.Chem.

Reference] Next, the present invention will be specifically explained with reference to Examples, but the present invention should not be construed as being limited by these Examples, which merely show specific reaction examples. Example 1 350 mg (5.0 mmol) of 1,2-epoxy-3-butene and 1.22 g (6.0 mmol) of allyltrimethyltin were added to an equimolar amount of 1,2-epoxy-3-butene in 30 ml of methylene chloride. The reaction was carried out at -78°C for 1 hour in the presence of boron diethyl etherate [BF 3 .O(C 2 H 5 ) 2 ], and then the reaction temperature was raised to -10°C over a period of 1 hour. After the reaction, water was added to the reaction solution to separate it into an organic layer and an aqueous layer, and the aqueous layer was extracted twice with 20 ml of diethyl ether. The organic layers were combined, washed twice with 15 ml of water, and then dried over anhydrous magnesium sulfate. According to gas chromatography (column 10% - Ucon oil LB550, internal standard n-heptanol), the yield was 91%, and as a result of comparison with the standard, the isomer ratio was >99.5:<
It turned out to be 0.5. Rotary organic layer
After concentrating with an evaporator, the residue was subjected to silica gel chromatography (developing solvent: hexane-diethyl ether mixed solvent), and the 3-(hydroxy) methyl)-1,
5-hexadiene was obtained (yield 448 mg, yield 80
%). The nuclear magnetic resonance spectrum and infrared absorption spectrum measured for this product were as follows. 1 H―NMR δ TMS CCl4 2.16 (br.m, 4H, CHCH 2

(m), 1635 (s, C=C), 990and910cm -1
(s, CH=CH 2 ) Example 2 The reaction was carried out in the same manner as in Example 1 except that aluminum chloride was used instead of boron trifluoride diethyl etherate, and 3-hydroxymethyl-1,
5-hexadiene was obtained with a yield of 52%. No formation of hepta-2,6-dienol was observed. Examples 3 to 9 3 mmol of the unsaturated epoxy compound shown in Table 1 and a predetermined amount of an organic tin compound were added to 15 ml of methylene chloride, and 3 mmol of boron trifluoride diethyl etherate was added to the resulting solution at -78°C. After reacting for 1 hour, the reaction temperature was slowly raised to -10°C (0°C in Example 9) over 0.5 hours. After the reaction was completed, the desired product was isolated by performing the same post-treatment and purification as in Example 1. Product purity was determined by gas chromatography (GC) and structural identification by NMR and
This was done through IR. The results are summarized in Table 1.
