A series of β‐amino esters were synthesized by the reaction of N‐tosyl aldimine or N‐hydroxy aldimine with bromoacetate by sonochemical Reformatskyreaction. The β‐N‐hydroxyamino ester was obtained and the formed sensitive hydroxylamino functionality was resistant under the reaction condition. The β‐lactam also was synthesized by the reaction of N‐p‐methoxy aldimine as reacting substrate under this
N-甲苯磺酰胺或N-羟醛胺与溴乙酸酯通过声化学Reformatsky反应合成了一系列β-氨基酯。获得了β- N-羟氨基酯,并且在反应条件下形成的敏感羟氨基官能团具有抗性。的β内酰胺也由反应合成Ñ - p -甲氧基醛亚胺作为底这个声化学的Reformatsky反应条件下反应。
