Reaction of N-arylsulfonylaziridines with dimethylsulfoniumethoxycarbonyl methylide: regio- and stereo-selective synthesis of 1-arylsulfonyl-2-ethoxycarbonyl azetidines
摘要:
Synthesis and characterization of 4-aryl-, 3,4-diaryl- and 3-alkyl-4-aryl-N-arylsulfonylazetidines, bearing a 2-ethoxycarbonyl group are described. The methodology used involves transfer of an ethoxycarbonyl substituted methylene group from dimethylsulfoniumethoxycarbonyl methylide to N-arylsulfonylaziridines. The synthesis is both regio- and stereo-selective.

We report a novel, simple, and efficient synthesis of aziridines and 1-chloroalkan-2-amines by the reaction of imines derived from various aldehydes and p-toluenesulfonamide or benzenesulfonamide with iodoor chloromethyllithium, respectively. Both halogenated anions were generated in situ by treatment of diiodo- or chloroiodomethane with methyllithium at -78 or 0 degrees C. The reaction of in situ generated iodo- or chloromethyllithium could also be performed from chiral 2-aminoaldimines to yield enantiopure aziridines or (2S,3S)-2,3-diamino-1-chloroalkanes with high stereoselectivity.

A Convenient Method for the Synthesis of 2-Arylaziridines from Styrene Derivatives via 2-Arylethenyl(diphenyl)sulfonium Salts
Styrene derivatives reacted with diphenyl(trifluoromethanesulfonyloxy)sulfonium trifluoromethanesulfonate (1) at low temperature to afford 2-arylethenyl(diphenyl)sulfonium triflates (2). Treatment of 2 with primary amines gave the corresponding 2-arylaziridines in high yields. One-pot synthesis of various aziridines was also successfully carried out without isolation of the intermediate 2.
