Novel One Pot Synthesis of 3-Acetyl-5-hydroxy-2-methylbenzofuran and 3-Acetyl-5-hydroxy-2-methylnaphthofuran and Synthesis of Their Derivatives

Abstract

The benzofurans and naphthofurans so far were obtained either by using catalyst or as side products. In the present investigation we are reporting first time the exclusive formation of only 3-acetyl-5-hydroxy-2-methylbenzofuran and 3-acetyl-5-hydroxy-2-methylnaphthofuran in quantitative yield by adopting the Nenitzescu reaction. Further, these 5-hydroxybenzofuran and 5-hydroxynaphthofuran were converted to their corresponding 5-methoxyl/5-methoxycarbonylmethoxy derivatives.
