A modification to the classic Diels–Alder [4 + 2] cycloaddition reaction, termed the pentadehydro-Diels–Alder reaction, is reported; this reaction generates a highly reactive intermediate, an α,3-dehydrotoluene, that can be captured using various trapping agents to produce structurally diverse products.
