摘要

The use of chiral dioxiranes, generated in situ from ketones and Oxone ® , is an extremely promising approach for the asymmetric epoxidation of 'unfunctionalised' alkenes. 1., 2., 3. and 4. Amongst several notable contributions, the fructose derived ketone 1 reported by Shi and co-workers 2 affords very high enantioselectivities for epoxidation of a range of alkenes. However, it suffers from decomposition by Baeyer–Villiger reaction under the reaction conditions, ...
