Abstract
A photoredox-promoted cascade glycosylation/cyclization reaction of 2-isocyanobiaryls and glycosyl NHP esters was established for the synthesis of nonclassical heteroaryl C-glycosides. This methodology is characterized by an exceedingly simple reaction system, high diastereoselectivity, and good functional group tolerance. In contrast to traditional strategies, this innovative approach circumvents the need for high temperature, transition metal, and photocatalyst, offering an environmentally friendly and efficient protocol.

Abstract
A benign electrochemical method to access 6-methylphenanthridines from 2-isocyanobiaryls using N,N-dimethylformamide (DMF) as a methyl source is reported. The protocol operates at ambient temperature without the need for harmful methylating reagents. Mechanistic studies suggested that DMF delivered a methylene synthon, followed by reduction at the cathode and tautomerization. The method offers environmental benefits by avoiding metal-based reagents and harsh conditions.
