Abstract

Laboratoire de Chimie Organique et Organometallique associe au CNRS, Universite Bordeaux I, F-33405 Talence, France ... Abstract: An efficient, direct and regioselective preparation of 2,2- dimethylcyclopentanone, via its enolate precursor regioselectively obtained using the 2-pynolidone magnesium salt, a base electrogenerated in DME/HMPA, is reported. ... Although a-alkylation of ketones via their metal enolates (M = Li, K, ...) is of
