Abstract:

The selective conversion of biomass-derived polyols into nitrogen-containing compounds remains a formidable challenge in sustainable chemistry. Although hydrogen borrowing strategies have emerged as environmentally benign alternatives to traditional reductive amination, precise control over selective C—C bond cleavage during polyol conversion persists as a significant difficulty. Herein, we report an approach utilizing distinct catalytic systems to regulate selective C—C bond cleavage of polyols, thereby generating diverse nitrogen-containing compounds. This system efficiently synthesizes quinoxaline and indole-type N-heterocyclic compounds under mild conditions without requiring external reducing agents. Substrate scope studies demonstrate that both electron-rich and electron-deficient aromatic amines and indole substrates afford the target products in moderate to excellent yields. This strategy overcomes the reliance of traditional reductive amination on harsh conditions and external reductants, thus providing a new, atom-economical, and environmentally benign pathway for biomass transformation.

Key words: Polyols, Hydrogen transfer strategy, N-heterocyclic compounds
