N,N-Diarylaminoallenes were synthesized by isomerisation of the corresponding propargyl derivatives and submitted to reaction with 3,5-dichloro-2,4,6-trimethylbenzonitrile oxide. 5-Diarylamino-4-methylene-4,5-dihydroisoxazoles were formed with full site selectivity and regioselectivity. These cycloadducts were susceptible to nitrile oxide cycloaddition onto the exocyclic double bond as well as to acid-promoted amino-Claisen rearrangement.
