[3-(Ethylthio)allyl]titanium reagent generated easily from allyl ethyl sulfides condensed with aldehydes to give erythro-β-hydroxy sulfides in highly regio- and stereoselective manner. In contrast, crotyl ethyl sulfide reacted with aldehydes affording δ-hydroxy vinyl sulfide exclusively. The substitution pattern of the starting sulfide can have a pronounced effect on the selectivity in this condensation reaction
Hydrozirconation of allenyl sulfide generates a γ-thio-allylzirconocene species, which reacts with aldehydes and ketones to give anti olefinic β-sulfenyl alcohols in highly regio- and stereoselective manner.
