摘要

Abstract 2-Styryl-1, 4-benzoquinone (1) and compounds 2 and 3 containing 1 as a substructure all proved to be highly reactive towards thermal or photochemical [4π+ 2π] cyclodimerization reactions. Chemo-, regio-and stereoselective processes lead to dimers (compounds 1− 10), which can undergo secondary reactions consisting of the addition of nucleophiles combined with a twofold keto-enol tautomerism (10⇄ 12). An alternative ...
