    摘要： New intermediate, an optically active (1R,5S,6S,7R)-6-tert-butyldiphenylsilyloxmethyl-7-hydroxy-bicyclo[3.3.0]octan-3-one (I) having high optical purity which is useful for the synthesis of an optically active carbacyclin and an optically active pentalenolactone E methyl ester. The compound (I) is also an intermediate compound serving for the purpose of improving the optical purity of (1R,5S,6S,7R)-3,3-ethylenedioxy-6-hydroxymethyl-7-(2'-tetrahydropyranyloxy)bicyclo[3.3.0]octane. The compound (I) is prepared by reacting (1R,5S,6S,7R)-3,3-ethylenedioxy-6-hydroxymethyl-7-(2'-tetrahydropyranyloxy)bicyclo[3.3.0]octane with tert-butylchlorodiphenylsilane in the presence of a base and removing the ethylenedioxy and tetrahydropyranyl groups of the resultant compound under an acid condition.

    摘要： New intermediate, an optically active (1S,5R)-7,7-alkylenedioxy-2-alkoxycarbonylbicyclo[3.3.0]octan-3-one which is useful for the synthesis of an optically active carbacyclin. This intermediate is prepared, as a non-reduced compound, from a racemic compound, (1SR,5RS)-7,7-alkylenedioxy-2-alkoxycarbonyl-cis-bicyclo[3.3.0]octane-3-one, by treatment of the racemic compound with a microorganism. The microorganism has an ability of specifically reducing the keto group of the (1R,5S) epimer of the racemic compound.
