Ketones phenylthiomethyllithium

Homologation Acrolein. Carbon monoxide. Cuprous bromide-Diazomethane. Ethyl bromo acetate. Ethyl diazoacetate. Methyl vinyl ketone. Phenylthiomethyllithium. Trimethyl phosphite. [Pg.514]

Phenylthiomethyllithium was also used for ketone methylenation, - mainly in the case of hindered ketones which do not react with the usual Wittig reagent. This is a three-step sequence the reagent (2a) is added, then the resulting alcohol is acylated, and finally the exocyclic methylene is formed by reduction with lithium in ammonia (Scheme 17). [Pg.139]
