164. Generally speaking, the control of the regioselectivity in the additions or cycloaddition reactions to the endocycclic double bond of a remote-substituted bicyclic system is an old question not yet well explained. For instance, some electrophilic additions show total regioselectivity depending on the nature of the remote substituent. In contrast, cycloaddition reactions such as 1,3-dipolar, Diels-Alder and Pauson-Khand have different levels of regioselectivity depending on both the remote substituent and the nature of the reagent involved in the reaction. These questions will be discussed in a next article of this serie.

166. All regioisomeric products were obtained as a diastereomeric E/Z mixture. In order to avoid complications in the determination of the regioselectivity the purified reaction mixtures were submitted to catalytic hydrogenation. As this last reaction was held in all cases with yields between 93-100 % the determination of the ratio of hydrogenated isomers may be consider as a convenient measurement of the regioselectivity of the reaction.
