Two series of enantiopure azobenzenes with a p-tolylsulfoxide at the ortho or meta position with respect to the azo group, have been regioselectively synthesized. Both can act as enantiopure molecular switches showing different structural features owing t

Optically pure (S)-p-tolylsulfinyl substituted quinones were synthesized by deketalization of the corresponding quinone bisketals obtained by Andersen's type synthesis starting from 2-bromo-1,4-dimethoxy aromatic derivatives, followed by anodic oxidation

Optically pure (S)-2-p-tolylsulfinyl-1,4-benzoquinone (5) is readily obtained by deketalization of the corresponding quinone bisketal 4, synthesized by Andersen's type synthesis on 2-bromo-1,4-dimethoxybenzene (1) followed by anodic oxidation of the resulting sulfoxide.The Diels-Alder reaction of cyclopentadiene with 5 took place on C5-C6 dienophilic double bond showing high facial selectivity, which can be inverted by using different Lewis acids, and total endo selectivity.
