Several anti-BVDV agents with a polymethylated gamma-carboline skeleton were synthesized, and their anti-BVDV activity was evaluated. The most potent antiviral agent, SK3M4M5M (20), was synthesized by Pd-catalyzed Buchwald-Hartwig amination reaction followed by annulation reaction as key steps. The structure-activity relationship was analyzed.

A Rh(iii)-catalysed C–H annulation of indolyl oximes with alkynyl silanes was developed, delivering diverse γ-carbolines with unexpected reverse regioselectivity.
