Several 6,7-dioxygenated (cis or trans) labdanes have been synthesised starting front sclareol. A new strategy that allows the obtention of diols alpha-cis as well as beta-cis of trans is described. In particular, the syntheses of three natural highly functionalised labdanes in the B rings of 2, 3 and 4 with different side chains are reported. The syntheses have permitted to Correct the proposed Structure for one of them. (C) 2008 Elsevier Ltd. All rights reserved.
