摘要：

The reactions of beta-keto sulfoxide, beta-keto sulfones, or beta-keto phosphinate with 1,1-disubstituted ethenes in the presence of manganese(III) acetate and molecular oxygen yielded 4-phenylsulfinyl-, 4-phenylsulfonyl-, or 4-phosphinoyl-1,2-dioxan-3-ols 3 in moderate-to-good yields. m-Chloroperbenzoic acid oxidation of 4-phenyl-sulfinyl-1,2-dioxan-3-ols gave the corresponding 4-phenylsulfonyl derivatives, The temperature dependence of the reactions was observed and the stereochemistry of the 1,2-dioxan-3-ols are discussed.
