TL;DR: In this article, the effect of substituents for orientation phenomena can be considered to be of electronic nature, and preliminary accounts for the Diels-Alder reaction of methoxybenzoquinone revealed that the effect on orientation properties can be assumed to be electronic.
Abstract: Total syntheses of tanshinone-II (II) and cryptotanshinone (III) from 3-methylbenzofuran-4, 7-quinone (X) and 6,6-dimethyl-l-vinylcyclohexene (IX), and of tanshinone-I (I) from quinone X and o-methylstyrene (XVIII) are described. Preliminary accounts for the Diels-Alder reaction of methoxybenzoquinone revealed that the effect of substituents for orientation phenomena can be considered to be of electronic nature.
