Article abstract of DOI:10.1246/bcsj.67.2507

In the photoaddition reaction of terpinolene with methyl 2,4-dioxopentanoate, the products derived from the tetrasubstituted C = C were four proto-[2 + 2] photocycloadducts, together with ene reaction products. When these proto-cycloadducts were treated w
