A stereoselective reaction followed by a sequential cyclization route has been used in the divergent synthesis of 1-hydroxyquinolizidione isomers. Sharpless asymmetric dihydroxylation afforded hydroxyl lactone and the following mesylation provided the required precursor for cyclization. (C) 2009 Elsevier Ltd. All rights reserved.
