1,6-Asymmetric induction in reactions between 6-hydroxy-5-methylhex-2-enyl(tributyl)stannane and aldehydes promoted by tin(IV) bromide

Add time:09/02/2019    Source:sciencedirect.com

(R)-6-Hydroxy-5-methylhex-2-enyl(tributyl)stannane 4 transmetallates on treatment with tin(IV) bromide to give an intermediate allyltin tribromide which reacts with aldehydes to give 1-substituted (Z)-6-methylhept-2-ene-1,7-diols 7 with excellent anti-1,6-asymmetric induction.
