Abstract:

The Mannich reaction of Ohira-Bestmann reagent and α-amino sulfone was preliminary studied with tetrabutyl ammonium iodide(TBAI) as a phase transfer catalyst. Under the optimal reaction conditions, the Mannich reaction between Ohira-Bestmann reagent and a series α-amino sulfone derived from substituted aromatic aldehyde can be smoothly achieved. Moderate to good yields(52%—93%) were obtained and the structure of β-aminophosphonate derivatives 5a—5k were confirmed by 1H NMR, 13C NMR and MS. By the Mannich reaction of Ohira-Bestmann reagent and α-amino sulfone, an effective method for the preparation of β-amino phosphonate derivatives was developed.

Key words: β-Aminophosphonate derivative, Mannich reaction, α-Amino sulfone, Phase-transfer catalysis
