Key Points

The aim is to synthesize 3-organoselenyl chromenones using a novel cyclization method.
Synthesis of 3-organoselenyl chromenones via cascade cyclization technique
Use of diorganyl diselenides and hydrogen peroxide as promoting agents
Successful synthesis of 3-organoselenyl chromenones was achieved
Catalysts significantly enhanced the cyclization process

Implication

Demonstrates the cyclization of aryl propargyl ethers in organoselenyl compounds, implying an efficient synthetic route.

Abstract

We report the synthesis of 3-organoselenyl chromenones via a cascade cyclization of organoselenyl arylpropargyl ethers. The method is promoted by diorganyl diselenides and hydrogen peroxide. In this process, diorganyl diselenides...
