The Synthesis of O-Silyl Ketene Acetals from α-Haloesters

α-Haloesters of the general structure R1R2CXCO2R3 1 have been shown to react with sodium in the presence of a halosilane 2 to yield the corresponding O-silyl ketene acetals 3 (SKAs) according to equation 4.The factor that most influences the yields in these reactions is the concentration of halosilane; if there is a deficiency of halosilane, then acyloin condensation products will detract from the yield of SKAs.The reaction is quite general, and often gives yields in excess of 90percent of the desired SKAs.

ETUDE DE LA REACTION CHLOROCARBENE-ACETALS DE CETENES. I. SYNTHESE D'ESTERS α,β-ETHYLENIQUES.

The reaction of chloro, chloromethyl and chlorophenyl carbenoids with ketene alkylsilylacetals has been studied.Excellent yields of cyclopropanation were observed and the unstable chlorocyclopropanone acetals formed were thermally rearranged in high yield into α-substituted α,β-ethylenic esters.This new method for the synthesis of unsaturated esters appeared complementary of the known-ones.
