Efficient synthesis of α-enaminophosphonates in the series of piperidine and morpholine: Examples of synthetic applications

Dufrechou,Combret,Malhiac,Collignon

, p. 1 - 14 (1997)

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.
