Intramolecular
Hydroamina04 - 072 tion/Cyclization of Amines Tethered to 1,2-Disubstituted Alkenes.
— Mono- and disubstituted pyrrolidines and piperidines are synthesized using
coordinatively unsaturated organolanthanoid complexes as catalysts which
can even mediate intramolecular hydroamination/ cyclization of sterically
demanding amino-olefins to afford the disubstituted pyrrolidine (X) in high
diastereoselectivity (94%).
