摘要: An efficient, clean and very simple procedure for the synthesis of protected β-amino acids is described. Michael addition sulfonamides to α,β-unsaturated esters in presence K2CO3 tetrabutylammonium bromide (TBAB) under microwave irradiation affords title compounds good high yields short reaction times. This new method
