Synthesis of novel condensed tricyclic systems from 2-alkenyl(alkynyl)thio-3-thiophenaldoximes
摘要:
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.
