The deprotonation of ketones and esters with lithium dialkylamides in the presence of trimethylchlorosilane leads to enhanced selectivity for the kinetically generated enolate. Lithium -octyl--butylamide is shown to be superior to lithiumdiisopropylamide in the regio-selective generation of enolates and in the stereoselective formation of enolates.

2-Oxoalkylated 1,4-naphthoquinones were obtained in the photochemicalreactions of 2,3-dichloro-1,4-naphthoquinone with 2-trimethylsiloxy-1-alkenes. Application of this method afforded a wide variety of functionalized 2-oxoalkylated 1,4-naphthoquinones. The photochemicalreactions of 2,3-dichloro-1,4-naphthoquinone with 1-alkyl-2-(trimethylsiloxy)ethylenes gave naphthol derivatives. However, 1,1-d
Abstract Efficient access to thermodynamically favoured silyl enol ethers deriving from α,α′-dienolizable ketones was produced via easy-made NEt3HCl-mediated isomerization of a regioisomeric mixture of O-silylated products. † deceased on 7 may 1997 § Present adress: Laboratoire de Synthese Organique, associe au CNRS, Universite du Maine, Avenue Olivier Messiaen, B.P. 9 F-72085 Le Mans (France)
