A NEW METHOD FOR THE PREPARATION OF β-(ALKYLAMINO)-CARBONYL COMPOUNDS BY REARRANGEMENT OF β-CHLOROIMINES VIA AZETIDINE INTERMEDIATES
The reaction of β-chloroimines with sodium methoxide in methanol gave rise to β-(alkylamino)- and β-(arylamino)-carbonyl compounds in high yield.The reaction mechanism for the generation of β-(alkylamino)- and β-(arylamino)-carbonyl compounds passes via a
