## Abstract A goldβcatalyzed olefin cyclopropanation reaction of propargyl esters with vinyl ester or vinyl sulfonamide derivatives was investigated for the synthesis of highly substituted cyclopropane derivatives in good diastereoselectivity. By varying the vinyl species, __trans__βcyclopentenyl e

UDC 547.322'572.1'479.07 2-(4-Alkylthiophenyl)-and 2-(4-phenylthiophenyl)pyrroles and their 1-vinyl derivatives were synthesized by the reaction of 4-alkylthio-and 4-phenylthioacetophenone oximes with vinyl chloride in a KOH-DMSO system at 120 and 130~ and at atmospheric pressure. As we know, sever
