A simple one-pot synthesis of hydroisobenzothiophenes three-step sequential pericyclic reactions of xanthates
摘要:
Thermolysis of O-(2,4-alkadienyl) S-(2-alkenyl or 2-alkynyl) dithiocarbonates (xanthates) gave the hydroisobenzothiophene derivatives via two sequential [3,3]-sigmatropic rearrangement followed by the intramolecular cycloaddition.
