Mercuric ion-induced intramolecular cyclization of 2-amino-4- alkenylamine derivatives. Stereoselective synthesis of 3-aminopyrrolidines
摘要:
Intramolecular amino- and amido-mercuration of delta-unsaturated-beta-amino-amines and carbamates afforded the corresponding 3-aminopyrrolidine derivatives in good yields (70-85%) and high stereoselectivity (> 95%).
