A one-carbon homologation of an alcohol to the extended carboxylic acid, ester, or amide involves a Mitsunobu reaction with an alkoxymalononitrile, followed by unmasking in the presence of a suitable nucleophile. The homologation and unmasking can even be performed in a one-pot process in high yield.
