Intramolecular nitrile oxide cycloaddition to functionalized furans occurs with complete regiochemical control but low diastereoselectivity. The poor reactivity of furan as 2 3Z component in the 1,3-dipolar cycloaddition with nitrile oxide' greatly limited its practical use in this reaction. 2,3 Thi

Here, we report the cycloaddition reaction of phosphonyl nitrile oxides and the formation of an unexpected 2:1 cycloaddition product. It provides a direct route to triphosphonyl-substituted dihydroisoxazolyl dihydroisoxazoles and diphosphonylsubstituted dihydroisoxazolyl dihydroisoxazoles with excel

Cycloaddition of nitrile oxides to 4-vinyl-2-oxazoline 1 and to 4-vinyloxazolidine 2 afford diastereomeric mixtures of 2-isoxazolines in which the eryrhro product predominates (32-64% d.e.). In contrast, the cortesponding reactions with acyclic analogue 3 favoured the fhreoadducts and were less sele
