Abstract

La cyclisation selon Fischer d'arylhydrazones d'oxo-1,2 et 3 alkylphosphonates permet d'acctderi à divers indole phosphonates 1–5. Les acides phosphoniques correspondants 1′-5′ ont Cgalement été préparés. Les structures des différents indoles sont confirmées par spectroscopie RMN31P, 1H et 13C.

The Fischer cyclization of 1,2,3-oxoalkylphosphonates arylhydrazones into indole phosphonates 1–5 is described. The corresponding phosphonic acids 1′-5′ are also prepared. The structures of these indoles have been determined by 31P, 1H and 13CNMR spectroscopy.
