Key Points

This research focuses on developing a catalyst-free method to synthesize α-carboline derivatives using chromone structures.
Catalyst-free [3+3] annulation of indolin-2-imines with 3-formylchromones was conducted.
The chromone undergoes ring-opening followed by reorganization to form α-carboline derivatives.
Successfully synthesized functionalized α-carboline derivatives through the proposed method.
Demonstrated the viability of chromone remodeling without the use of catalysts.

Implication

Explores catalyst-free synthesis of α-carboline derivatives, indicating innovative methods in organic chemistry.

Abstract

A catalyst-free [3+3] annulation of indolin-2-imines with 3-formylchromones is developed to synthesize functionalized α-carboline derivatives. The chromone six-membered oxacycle undergoes ring-opening and reorganization, with its three-carbon unit embedded into the...
