Effect of CH/pi interaction on exo/endo selectivity in 1,3-dipolar cycloadditions
Original language description
In order to prove our assumption about the role of CH/pi interaction in preferential formation of exo-isomers, we varied proton affinity of the aromatic ring of 1,3-dipolar nitril ylide reagent introducing para-substituents. Indeed the reactions of 1a with such substituted nitrile ylides yielding mixtures of diastereomers exo-2 and endo-2 showed that the amounts of endo-adducts increased with increasing electron withdrawing character of the substituents Z.
