  one-carbon homologation of carbonyl compounds is described. The method is based on the rearrangement of β-oxido carbenoid which is generated via the ligand exchange reaction of the sulfinyl group of α-chloro β-hydroxy sulfoxide with tert-butyllithium. Addition of the carbanion of aryl 1-chloroalkyl sulfoxides to carbonyl compounds gave the adducts in good yields. The β-oxido carbenoid rearrangement of the

  aziridinyllithiums having several alkyl groups were investigated. As an extension of this method, a synthesis of α,α-dialkylamino acid esters, including an optically active form, and amides was realized via the aziridinyllithiums. N-Non substituted α,α-dialkylamino acid esters were synthesized starting from N-(4-methoxyphenyl) aldimine.
