Description
Li and Noble couple aldehydes with electron poor olefins using light and a Hantzsch ester in twenty twenty-six. Both partners are cheap feedstocks, and their union yields prized alcohols. Past routes needed harsh reducing power that let side paths win. Aliphatic aldehydes failed most often. Their setup skips any photocatalyst.
Light wakes the ester anion under mild base, and it reduces the olefin. Water as an additive lets the charged olefin attack the aldehyde. Tests back the olefin radical anion as the key middle step. The simple recipe widens who can play, they argue.
