2,4-Disubstituted N-tosylpyrrolidines were prepared from olefins via N-tosylaziridination, benseneselenolate ring-opening and reductive radical cyclization. Azidoselenation of olefins, followed by reduction, N-tosylation, N-allylation and reductive radical cyclization, afforded 3,4-disubstituted N-tosylpyrrolidines. (C) 1998 Elsevier Science Ltd.
