Various α-piperidino or α-morpholino alkenylphosphonates are conveniently prepared from the related α-hetero-substituted methylphosphonates, through a Peterson olefination process, which can be easily adapted for a direct homologation of aldehydes into carboxylic acids. An efficient synthesis of α-piperidino or α-morpholino alkylphosphonates and phosphonic acids is proposed.
