    摘要： The invention relates to a method for producing cis-cyclopent-4-ene-1,3-diol and cis-cyclopent-4-ene-1,3-dialkanoates by selective cis-1,2-reduction of 4-hydroxycyclopent-2-enone (I) by means of a hydroboron (II), in the presence of substoichiometric quantities of a trivalent rare earth metal compound (III), to form cyclopent-4-ene-1,3-diol (IV) which can then be optionally reacted with an acylation agent (V) to form cis-cyclopent-4-ene-1,3-dialkanoates (VI), in order to simplify the reprocessing and without intermediate isolation.

    摘要： In the present invention, an optically active cis type 1,2-diol derivative of the following formula (I) is produced by reacting a cis type 1,2-diol derivative of the formula (I) with a carboxylic acid derivative of the formula (II) in the presence of a lipase:

    wherein R 1 and R 2 independently represent hydrogen atom or an alkyl group, X represents a halogen atom, a nitro group, a cyano group, an alkyl group, a haloalkyl group, or a phenyl group, and n represents an integer of from 0 to 5; R 3 represents a C 1 - C 10 alkyl group or an aryl group, and R 4 represents a hydrogen atom, a C 1 - C 5 alkyl group, a C 2 - C 4 alkenyl group, or COR 3 . The cis type means that the bond between the cyclopentane ring and the hydroxy group and the bond between the cyclopentane ring and the benzyl group reside in the same direction as that portrayed on the paper. The optically active cis type 1,2-diol derivative is used as an intermediate for producing an optically active cis type azole derivative of the formula (VII).
