Treatment of 1,2-diazetidin-3-one with acid chlorides in the presence of 2,6-lutidine led to 1,2-diacyl-1,2-diazetidin-3-ones (N,N-diacylation), while the use of triethylamine as base gave 1-acyl-3-(acyloxy)-1,4-dihydro-1,2-diazetes (N,O-diacylation).Several 1-benzhydryl-2-acyl-1,2-diazetidin-3-ones were found to rearrange smoothly upon treatment with ethyl chloroformate to give 2-substituted 4-benzhydryl-4,5-dihydro-1,3,4-oxadiazin-6-ones.
