Diastereoselective oxidative cyclization of 1,4-dienes for the synthesis of oxetanes
Abstract
In this paper, an osmium catalyzed oxidative cyclization of 1,4-dienes is reported. The reaction undergoes exo,exo-type cyclization, with oxetanes obtained for the first time as oxidative cyclization products. Catalytic amount of potassium osmate dihydrate was used with sodium periodinate as a terminal oxidant.
