Abstract

Abstract The ozonolysis of 1-substituted allyl silyl ethers or 1-substituted allyl carboxylates followed by treatment with bases gave the corresponding α-silyloxymethyl-or α- acyloxymethyl-ketones in good yields. It is proposed to proceed via the corresponding α- silyloxy-or α-acyloxyaldehydes intermediates followed by 1, 4-group migration. The results of theoretical calculations are applicable to explain the experimental results.
