3-Indolylacyl Radical Cyclizations upon Pyridines and Tetrahydropyridines: Access to Ergoline-Related Indole [cd]-fused Isoquinolines
摘要:
Cyclizations of selenoester-derived 3-indolylacyl radicals, involving the homolytic acylation of pyridines or the addition to double bonds included in tetrahydropyridine rings, have been used to synthesize indole [cd]-fused isoquinolines related to the natural ergoline system.
