Synthesis of δ-Carbolines via a Pd-Catalyzed Sequential Reaction from 2-Iodoanilines and <i>N</i>-Tosyl-enynamines

A facile Pd-catalyzed sequential reaction has been developed for the synthesis of δ-carbolines from 2-iodoanilines and N-tosyl-enynamines. This protocol involves Larock heteroannulation/elimination/electrocyclization/oxidative aromatization cascade sequences and allows access to multisubstituted δ-carbolines in moderate to good yields

Synthesis of 3‑Alkyl- or 3‑Allenyl-2-amidobenzofurans via Electrophilic Cyclization of <i>o</i>‑Anisole-Substituted Ynamides with Carbocations

A facile carbocation-induced electrophilic cyclization reaction has been developed for the synthesis of 3-alkyl- or 3-allenyl-2-amidobenzofurans from o-anisole-substituted ynamides and diarylmethanol or 1,1-diarylprop-2-yn-1-ol
