Formation of β-Substituted γ-Keto Esters via Zinc Carbenoid Mediated Chain Extension

Abstract

The conversion of β-keto esters into β-methylated γ-keto esters can be achieved through treatment with zinc carbenoids derived­ from 1,1-diiodoethane. The incorporation of a β-phenyl substituent is also possible through treatment with diiodotoluene.

carbenoids - diiodoethane - esters - chain extension - zinc

When carbenoid 7 was prepared in the absence of the β-dicarbonyls and allowed to stand for 2 h prior to quenching by the addition of aqueous acid, 2-iodo­-butane was isolated in 54% yield
