acrolein and 2-methylcyclohexanone to produce the corresponding β-hydroxysilanes in good yield, but with only a 3–4% diastereomeric excess. Unfortunately, these diastereomers proved impossible to separate. Model studies employing the methyldiphenylsilyl group showed that these β-hydroxysilanes could be protiodesilylated to give the corresponding methyl alcohol. The products from the adduct with pivaldehyde
