摘要：
Reaction of the iminophosphoranes (7)-(9), derived from α-azidocinnamates and triphenylphosphine, with aromatic isocyanates gives either 1-arylaminoisoquinoline-3-carboxylates (10)-(12) or the corresponding carbodi-imides (14)-(18) which by thermal treatment at 230°C are converted into 1-(N-aryl-N-imidazolylamino)isoquinoline-3-carboxylates (19)-(20). The iminophosphoranes (7) and (8) also react with aroyl chlorides to give the oxazolone derivatives (23)-(26).
