The preparation of 2-(arylmethoxy)isopinocampheols from pinanediol via the DIABL-H reduction of the corresponding aryl aldehyde acetals has been described. A systematic examination of the asymmetricaldol reaction of 3,3,3-trifluoropropionates led to the double diastereoselective aldol reaction of 2-(arylmethoxy)isopinocampheyl 3,3,3-trifluoropropionates providing anti-α-trifluoromethyl-β-hydroxy esters
