1,4,2-Dioxazines or N-acyl isoxazolidines from organoselenium-induced cyclisation of O-allyl hydroxamic acids
Abstract
O-Allyl hydroxamic acids easily give rise to organoselenium-induced cyclisation reactions to afford phenylseleno-substituted 1,4,2-dioxazines or N-acyl isoxazolidines as the kinetically or thermodynamically controlled products, respectively.
