a-Keto acid derivatives are versatile intermediates in organic synthesis. Previously, we have described several methodologies for the synthesis of these compounds, including cyanation of acyl chlorides, cyanocarbonylation of organic iodides, and double carbonylation of organic halides in the presenc
