Syntheses with carbanions derived from carbonyl-stabilized ylides; products from reaction of lithio-dervatives of dimethysulphonium diacetylmethylide
Abstract
The lithio-derivative prepared from dimethyl-sulphonium diacetylmethylide and n-butyl-lithium, reacted with a series of electrophiles to give alkylated and/ or cyclic products.
