CARBON-CARBON BOND FORMATION UNDER MILD CONDITIONS VIA TANDEM CATIONIC AZA-COPE REARRANGEMENT-MANNICH REACTIONS. A CONVENIENT SYNTHESIS OF POLYSUBSTITUTED PYRROLIDINES.

Article abstract of DOI:10.1021/ja00360a013

The reaction of aldehydes (or ketones) with 2-alkoxy(or hydroxy)-3-alkenamines achieves a general and high-yielding synthesis of polysubstituted 3-acylpyrrolidines (eq 5-9). This tandem cationic aza-Cope rearrangement-Mannich cyclization reaction (eq 1) o
