Abstract
2-(1-Alkylthio-2-cyanoethenyl)pyrroles were synthesized in good to hig h yields by reaction of pyrrole-2-dithiocarboxylates with active methy lene nitriles in a KOH-DMSO medium. The condensation of 4,5,6,7-tetrah ydroindole with cyanoacetate also leads to ,5,6,7-tetrahydrocyclohexa- [c]-3H-pyrrolizin-3-one in 61% yield. The effect of substituent on the reaction course has been studied. The dipole moments and spectral cha racteristics of products are presented.
