title: Rhodium-catalyzed transannulation of N-sulfonyl-1,2,3-triazoles and epoxides: regioselective synthesis of substituted 3,4-dihydro-2H-1,4-oxazines.
abstract: Rhodium-catalyzed transannulation of 1,2,3-triazoles and ring-opening reactions of epoxides is described. A number of 3,4-dihydro-2H-1,4-oxazines are obtained in moderate yields probably involving generation of α-imino rhodium(II) carbene species.
