Proper choice of Lewis acid and hydroxyl protecting group allows for selective addition of crotyltri-n-butylstannane to either face of the aldehyde carbonyl in derivatives of 2-methyl-3-hydroxypropanal with preservation of erythro selectivity for the bond

The role of the double bond geometry (E/Z stereochemistry) in reactions of crotylstannanes with aldehydes has been examined for representative "simple", α-alkoxy, and β-alkoxy aldehydes.For the reaction of crotylstannane with simple achiral aliphatic, aro
CROTYLZIRCONIUM DERIVATIVES AS A NEW REAGENT FOR THE THREO SELECTIVE SYNTHESIS OF β-METHYLHOMOALLYL ALCOHOLS

Crotylzirconium derivatives, prepared from the reaction of crotylmagnesium chloride or crotyllithium with bis(cyclopentadienyl)zirconium dichloride, undergo a rapid reaction with aldehydes to afford the threo product predominantly.The ratio of Cram/anti-Cram product via this reagent is ca. 75/25 ca. 60/40.
