The directenantioselective hydroxymethylation of aldehydes utilizing α,α-diphenylprolinoltrimethylsilylether as an organocatalyst is described. The intermediate α-substituted β-hydroxyaldehydes were not isolated but converted to the more readily isolable derivatives. For example, the derived hydroxy acids were isolated in up to 94% yield with excellent enantioselectivity.
