Anodic alkoxylation of lactams followed by reactions with carbon nucleophiles in a one-pot manner using HFIP as a solvent

Abstract

We have demonstrated anodic alkoxylation of lactams followed by reactions with carbon nucleophiles in a one-pot manner using 1,1,1,3,3,3- hexafluoroisopropanol (HFIP) as a solvent. In the two-step transformation, HFIP acted as a nucleophile in the presence of solid-supported bases, while it acted as an inert solvent in the absence of solidsupported bases. This enabled us to conduct anodic alkoxylation of lactams and subsequent C-C bond forming reactions without replacing the solvent.
