Diastereoselective synthesis of 1,8-trans-1-substituted and 5,8-trans-5-substituted tetrahydropyrrolo[1,2-c]oxazoles was achieved by an application of α-acylaminoradical cyclization at a silylated triple bond. The method was applied to an enantioselective synthesis of the 1,8-trans-oriented 1-oxygenated pyrrolizidine.
