Cyclization of N-Substituted 2,2-Diarylglycolohydroxamic Acids to 1,2-Oxazetidin-3-ones

Under mild conditions the reaction of N-substituted 2,2-diarylglycolohydroxamic acids 1 with 1,1'-carbonyldiimidazole (CDI) gives either directly 1,2-oxazetidin-3-ones 3 or 1,5,2-dioxazinane-3,6-diones 2 which undergo ring contraction to give 3 in boiling
