Abstract

The utility of the cyanohydrin diethylphosphates derived from aldehydes (arylaldehydes, crotonaldehyde, and cinnamaldehyde) as an acyl anion equivalent was examined. Deprotonation of cyanophosphates with n-butyllithium in the presence of tetramethylethylenediamine in tetrahydrofuran at-78° C followed by reactions with alkyl (acyl) halides, carbonyl compounds, and α, β-unsaturated nitriles or esters, as well as ...
