Synthesis of novel 2‐substituted‐5‐oxycoumarans <i>via</i> A direct route to 2,3‐dihydro‐5‐hydroxy‐2‐benzofuranacetic acids

Abstract

Abstract A number of novel 2‐substituted 2,3‐dihydro‐5‐benzofuranols optionally protected on 5‐OH group have been prepared via a simple two step route to racemic 2,3‐dihydro‐5‐hydroxy‐2‐benzofuranacetic acids from hydroquinones and 4‐bromocrotonates.
