Lithiated anions (9) or (10) of secondary or tertiary α-amidophosphonates are prepared either by reaction between an α-phosphonyl carbanion and an isocyanate or a carbamate (first strategy), or by condensation of an amide enolate with diethylchlorophosphate (second strategy).Acidic hydrolysis of (9) or (10) gives α-amidophosphonate (1) alkylated or not in the α-position. (9) and (10) react with aromatic or aliphatic aldehydes to produce α,β-unsatured secondary or tertiary amides (2).
