Significance
A reductive aldol reaction of enones to ketones is described. The reaction is catalyzed by dibutylhalgenotin hydride and employs diphenylsilane as the stoichiometric reductant. The reaction is applicable to a number of carbonyl compounds, including aldehydes, ketones, α-keto esters, α-alkoxy ketones and α-halo ketones. Tertiary carbinols can be obtained with high syn selectivity.
