Abstract Masked o-benzoquinones (MOBs), which were generated in situ from 2- methoxyphenols, underwent Diels–Alder reactions with 1-vinylcyclohexenes to produce the corresponding cycloaddition products, that is, decahydrophenanthrenes along with bicyclo [2.2. 2] octenones. In the former case, the MOBs serve as the dienophile, and in the later case, the 1-vinylcyclohexenes act as the dienophile. The obtained bicyclo [2.2. 2] ...
