One Approach to Cyclic Carbonates via a Three-Component Cyclization of Phenacyl Bromide, CO₂, and Aldehyde

Abstract

A three-component cyclization reaction was designed for synthesizing cyclic carbonates in a single operation from phenacyl bromide, CO(2), and aldehyde in the presence of lithium diisopropylamide (LDA). These novel reactions were achieved under extremely mild conditions to generate the target products in moderate to good yields within 10 min.
