Chemoselective Synthesis of β-Amino Ester or β-Lactam via Sonochemical Reformatsky Reaction

[[abstract]]A series of β-amino esters were synthesized by the reaction of N-tosyl aldimine or N-hydroxy aldimine with bromoacetate by sonochemical Reformatsky reaction. 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 sonochemical Reformatsky reaction condition.[[notice]]補正完畢[[incitationindex]]SCI[[booktype]]電子版[[booktype]]紙
