Preparation and Diels-Alder/cross coupling reactions of a 2-diethanolaminoboron-substituted 1,3-diene

A 2-diethanolamine boronyl substituted 1,3-diene has been synthesized in high yield and characterized spectroscopically as well as by X-ray crystallography. This diene has then subsequently been used in a number of fast, high yielding Diels–Alder/cross coupling reactions.
