Various alpha-piperidino or alpha-morpholino alkenylphosphonates are conveniently prepared from the related alpha-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 alpha-piperidino or alpha-morpholino alkylphosphonates and phosphonic acids is proposed.
