Iridium‐Catalyzed C5‐Regioselective Esterification of Dienyl Alcohols with Carboxylic Acids

Abstract

AbstractOne‐step process for the preparation of a 1,3‐dienyl‐5‐ester motif from readily available substrate remains a challenging work in organic synthesis. We herein report the first example of C5‐regioselective esterification of unactivated dienyl alcohols, using free carboxylic acids as nucleophiles under mild conditions, providing a series of 1,3‐dienyl‐5‐ester compounds in excellent regioselectivity and E‐selectivity.
