Nadir, Upender K. published the artcileA facile synthesis of N-arylsulfonylazetidines through the reaction of N-arylsulfonylaziridines with dimethyloxosulfonium methylide and a PTC [phase-transfer catalyst], Product Details of C3H9ClOS, the publication is Indian Journal of Chemistry, Section B: Organic Chemistry Including Medicinal Chemistry (1993), 32B(2), 297-8, database is CAplus.
N-Arylsulfonylazetidines (I; R1 = e.g., H, C6H4Me-p; R2 = alkyl, aryl) can be prepared in 18-55% yield by the reaction of corresponding aziridines (II) with dimethyloxosulfonium methylide in the presence of a PTC (e.g., tetrabutylammonium hydrogen sulfate). Aziridines substituted at positions 2 and 3 failed to react.
