Optically active diaryl diselenides carrying C2 symmetrical chiral pyrrolidines are synthesized by the condensation between 2,2′-diselenobis(benzyl chloride) derivatives and chiral pyrrolidines and are applied to methoxyselenenylation of trans-olefins. The observed diastereomeric excess (d.e.) is up to 60%.
