Allyl ethers of the tricarbonylchromium(0) complexes of benzylic alcohols undergo highly enantioselective benzylic functionalisation using a chiral base/electrophilic quench sequence; the allyl group is readily removed to reveal a hydroxy group as demonstrated in the syntheses of enantioenriched imidazole alcohols, a triol and a tertiary alcohol.
