stereoselectivity are discussed. Reaction of the oxaziridines with iron(II) sulfate, tributyltinhydride, or copper(I)triphenylphosphine chloride tetramer gave products arising from deoxygenation in many cases; however the trans-isomers also gave products derived from cyclisation of the intermediate aminyl radicals onto the pendant alkenyl chains.

Some 6-oxa-1-azabicyclo[3.1.0]hexanes have been prepared by photoisomerisation of alkenyl nitrone esters and peracidoxidation of pyrrolines Their ring-opening reactions with iron(II) sulfate, tri-n-butyl tin hydride and copper(I)triphenylphosphine chloride in many cases afford the related pyrrolines, but some trans oxaziridines give products derived from the trapping of aminyl radicals by the pendant
