Racemic homoallylic alcohols 1-3 containing dithioketeneacetal functionalities were prepared by addition of aldehydes to the allylic anions of ketene dithioacetals or 2-alkenyl-1,3-dithiane in a regio- and stereoselective manner. Lipase-catalyzed hydrolyses of the corresponding acetates 7-9 afforded optically active alcohols 1-3, which were treated with mercuric chloride to give γ-lactones such as natural hop lactone, whiskey lactone, and cognac lactone.

The reaction of 1-acyl-2,2-dichlorocyclopropanes with sodium thiophenolate in methanol leads to the products from nucleophilic substitution of the chlorine atoms with retention of the cyclopropane ring.The obtained 1-acyl-2,2-di(phenylthio)cyclopropanes i
