    • General Procedure for the Formation of Phosphonate 5: To acyl chloride 1 (2 mmol) was added neat trialkyl phosphite (1 equiv, The mixture was stirred under argon for 30 min. Toluene (1 M, isocyanide (1 equiv) and carboxylic acid (1 equiv) were then successively added. The mixture was stirred for 24 h under argon at r.t, for alkyl acyl chlorides) or at 80°C (for aromatic acyl chlorides, The solvent was then removed under reduced pressure to afford Passerini products after purification by flash column chromatography on silica gel.
