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%).
The presence of an amino substituent at the 2-vinyl position in substituted allyl vinyl ethers facilitates low-temperature rearrangements through [3,3]- or [1,3]-sigmatropicshifts, which lead to the aminoaldehydes (3) and (5), respectively.
