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