Diastereoselective alkylation of chiral tin(II) enolates onto cyclic acyl iminium ion proceeded in a different chiral recognition mode from the case of onto the cyclic acyl imines . This new diastereoselective alkylation was efficiently utilized for an asymmetric totalsynthesis of (−)-supinidine ().
