New di-, tri-, tetra-, and pentanorlabdane compounds with thiosemicarbazone and 1,3-thiazole fragments were synthesized. Their antifungal and antibacterial activities were studied. The main advantages of this research were the available starting material, i.e., the natural labdane diterpenoid (–)-sclareol, which was isolated from renewable resources, and the high probability of biological activity combined with the low toxicity of these compounds because of their natural origin.
Three labdane type diterpeneglycosides (, and ) with 6-deoxy-L-idose have been isolated fromAsterspathulifoliusMaxim. and their structures have been determined on the basis of chemical and spectral data.

The title compound 1 was prepared in 74% overall yield (3 steps) fromsclareol 2. The key step involves osmium tetroxide catalysed rearrangement to 4a and b during the oxidative degradation of sclareol.
