Transformations des énamines α-formylées: synthèse d’α-amino esters N,N-disubstitués

2-Dialkylaminoalkanoic esters are prepared in moderate yield by the reaction of N,N-disubstituted 2-amino-2-alkenals with dialkyl phosphonates in the presence of sodium alcoxide. A mechanism involving an α-keto-β-aminophosphonate as an intermediate is proposed.
