Ozonolysis of vinyl ethers in the presence of .alpha.-diketones and .alpha.-keto esters
摘要:
Ozonolysis of vinyl ethers in the presence of alpha-diketones provided two types of products, i.e., a Baeyer-Villiger oxidation product and 3-acyl-1,2,4-trioxolane. The evidence suggests that the latter product is labile and, therefore, the former one might be produced by decomposition of the latter. In contrast, 1,2,4-trioxolane-3-carboxylates were stable. As a result, ozonolysis of vinyl ethers in the presence of alpha-keto esters yielded the expected ozonides in high yield.
