Catalytic carbonylation of 3-bromometbyl-5,6-dihydro-4H-1,2-oxazines: General approach to the synthesis of 3-methoxycarbonylmethyl-5,6-dihydro-4H-1,2-oxazines from available precursors

摘要

A general approach to the stereoselective synthesis of previously unknown 5,6-dihydro-4H-1,2-oxazine-3-yl acetates by catalytic carbonylation of available 3-bromomethyl-5,6-dihydro-4H-1,2-oxazines is elaborated.
