Synthesis of substituted 3-thiophenecarbaldoximes containing unsaturated groups at C2
摘要:
A convenient preparative method was developed to obtain substituted 2-allylthio-5- methyl-3-thiophenecarbaldoximes, which are starting compounds in the synthesis of fused heterocycles containing the thiophene ring, by the successive action of sodium in liquid ammonia and substituted omega-halopropenes on 2-methylthio-5-methyl-3-thiophenecarbaldoxime.

Starting from 2-alkenyl(or alkynyl)thiothiophen-3-aldoximes, some novel tricyclic systems have been obtained which incorporate annelated thiophene, dihydrothiopyran, and isoxazoline or isoxazole rings.
