Chalcones to functionalized azetidines via anion-induced cyclization using task-specific ionic liquids
The first example of the application of task-specific ionic liquids (TSIL) to a new and practical synthesis of functionalized azetidines is reported. Aza-Michael addition of diethyl N-arylphosphoramidates to chalcones affords diethyl N-aryl-N-(1,3-diaryl-
