Protected 1,2,3-triols were prepared by organocatalytic alpha-hydroxylation of beta-hydroxyaldehydes followed by in situ reduction. All diastereoisomers were obtained with correct yields and good to excellent de. The absolute configurations of the new asymmetric centers were confirmed by derivatization into the corresponding epoxide. (C) 2012 Elsevier Ltd. All rights reserved.
