Addition of Bu3SnLi to tert-Butanesulfinimines as an Efficient Route to Chiral, Nonracemic α-Aminoorganostannanes

Addition of Bu3SnLi to tert-Butanesulfinimines as an Efficient Route to Chiral, Nonracemic α-Aminoorganostannanes

Addition of Bu3SnLi to tert-butanesulfinimines proceeds with high diastereoselectivities to provide the expected adducts in excellent yields and typically with dr = >99:1. These adducts are readily converted to enantiomerically enriched N-Boc-protected α-aminoorganostannanes with complete retenti...

Zusammenfassung:Addition of Bu3SnLi to tert-butanesulfinimines proceeds with high diastereoselectivities to provide the expected adducts in excellent yields and typically with dr = >99:1. These adducts are readily converted to enantiomerically enriched N-Boc-protected α-aminoorganostannanes with complete retention of configuration.
