Abstract
Aldehydes and primary alcohols can be converted via tricholormethyl carbinols to one-carbon homologated primary, secondary, or tertiary amides. The approach tolerates (hetero)aryl, alkyl, alkenyl, and racemizable chiral substrates, offers the opportunity to employ unprotected amino acids as amine sources and enables the preparation of Weinreb amides from aryl and unhindered aliphatic substrates.
