Av. Samet et al., REACTIONS OF SULFUR YLIDES WITH ALPHA,BETA-UNSATURATED THIOAMIDES - SYNTHESIS OF DIHYDROTHIOPHENES AND CYCLOPROPANES, Russian chemical bulletin, 47(1), 1998, pp. 127-133
The reactions of stabilized sulfonium ylides with arylmethylenecyanoth
ioacetamides proceed stereoselectively to yield 2-amino-4,5-dihydrothi
ophenes and cyclopropanethiocarboxamides. The structures, of the latte
r compounds were confirmed by X-ray diffraction analysis.
