Abstract

Easily accessible 2‐benzoylamino‐3,3‐dichloroacrylonitrile, when treated successively with primary amines, phosphorus pentachloride, sulfur dioxide, and various N‐ or S‐nucleophiles, furnishes the corresponding derivatives of 1,2‐dihydro‐2λ^5^‐[1,3]oxazolo[5,4‐d][1,3,2]diazaphosphinine, a novel fused heterocycle. The structure of the compounds obtained is unequivocally confirmed by spectroscopic methods and X‐ray diffraction analysis. © 2008 Wiley Periodicals, Inc.
