Substituent-controlled annuloselectivity and stereoselectivity in the sulfa-Staudinger cycloadditions

In the sulfa-Staudinger cycloadditions of imines and sulfonyl chlorides, the annuloselectivity is mainly controlled by the electronic effect of the α-substituents of sulfonyl chlorides and the nucleophilicity of imines. Sulfonyl chlorides with weakly elec

Synthesis and Configuration of 4-Alkyl-2-methyl-3,4-diphenyl-1,2-thiazetidine 1,1-Dioxide

4-Alkyl-2-methyl-3,4-diphenyl-1,2-thiazetidine 1,1-dioxide 5, 6 and 7 were obtained from 2-methyl-3,4-diphenyl-1,2-thiazetidine 1,1-dioxide 1 by reaction of its anion 4 with alkyl halides. cis- and trans-Configuration of 4-alkylated products were determined by 1H-nmr and NOE difference spectroscopy studies.
