Hetero-Diels-Alder reactions of (isobenzo)furans

Abstract

Hetero-Diels-Alder reactions of furans and isobenzofurans provide convergent redox-neutral access to hetero-oxanorbornene derivatives. These versatile intermediates serve as precursors to a variety of heterocycles, polymers, and complex natural products. Herein we comprehensively review this area of research and speculate on what developments are required to advance the field.
