The catalytic decarbonylation of aldehydes has become a well-known reaction since its discovery by Tsuji and Ohno. [¹] We previously used this reaction in a new strategy to access chiral building blocks in high optical purity, using the aldehyde as a removable steering group. [²] More recently, Madsen has used the catalytic decarbonylation of unprotected aldoses to generate polyols. [³] Herein we describe a procedure for the decarbonylation of epoxyaldehydes ...
