Abstract: Diastereoselective alkylation of chiral tin (II) enolates l_onto cyclic acyl iminium ionLproceeded in a different chiral recognition nicde from the case of&onto the cyclic acyl imines 5 This new diastereoselective alkylation was efficiently utilized for an asymmetric total synthesis of (-)-supinidine (g>,
