Abstract

NEW MATERIAL:An optically active compound of formula I [R1 is H or OH-protecting group; X is CHO, CH(SR2)2, etc.; R2 is alkyl, aryl; R3 is alkylene; the dotted line represents α-configulation; the thick solid line represents β-configuration; the wavy line represents α-configuration, β-configuration or their mixture].
EXAMPLE: (3aR,5R,6aS)-4-Bis(ethylthio)methyl-5-hydroxymethyl-2-oxo-hexahydro- 2H-cyclopenta(b)furan.
USE: A synthetic intermediate of a medicine such as an optically active prostaglandin.
PROCESS: The compound I is prepared by reacting the optically active compound II (Z is O, S; R4 is H, alkyl, aryl) with a thiol compound III or IV in the presence of an acid, and if necessary hydrolyzing the produced thioacetal.
