The preparation of a variety of highly substituted pyrrolidines was achieved by solid-phase synthesis through the [2rts + 4~s] cycloaddition of 2-azaallyl anions with alkenes. Resin-bound aldehydes 2 were condensed with ct-arnino stannanes 3 to afford (2-azaallyl)stannanes 4. Transmetalation of 4 wi

A highly functionalized perhydroindole is formed by the intramolecular [Ο€4s+Ο€2s] cycloaddition of a 2-azaallyl anion with a vinyl sulfide [Eq. (a)]. This is the key step in the total synthesis of (+)-coccinine, the enantiomer of the Amaryllidaceae alkaloid (-)-coccinine.
