Studies on heterocyclic chemistry. Part XIII. Cleavage of 5-benzyl-amino-oxazoles, photoproducts of N-benzyl-2H-azirine-2-carboxamides, by dialkyl phosphite
Abstract
N-Benzyl-2H-azirine-2-carboxamides were prepared by the photochemical or thermal isomerisation of 5-benzyl-aminoisoxazoles. Photochemical reaction of the 2H-azirines in dialkyl phosphite afforded benzamido-N-benzyl-acetamides via 5-benzylamino-oxazoles.
