Abstract
An efficient synthesis of acid-sensitive epoxides, such as chromene oxide or epoxide of γ, δ- unsaturated alcohol, was successfully achieved by the oxygenation of corresponding olefins with the combined use of an atmospheric pressure of molecular oxygen and aldoacetal catalyzed by a cobalt (II) complex coordinated with the 1, 3-diketone ligand. The reactions proceeded under mild and neutral conditions, and the desired epoxides were obtained in ...
