A Process for Synthesis of Bicyclic Ethers
Abstract

The invention presents a new method to synthesize bicyclic ethers and efficiently produce (±)-3’-hydroxy-5,7-dimethoxy-4-O-2’-cycloflavan. By reacting salicylaldehyde with 2-hydroxy styrene and trimethyl orthoformate in the presence of Lewis/Bronsted acid and organic solvent, the synthesis of bicyclic ethers is achieved. This process offers a streamlined approach to obtain valuable compounds with potential health benefits and biological activities, contributing to advancements in pharmaceuticals and science.
