A method was elaborated for the synthesis of polyfunctional compounds of the drimane series, viz., drim-8(9)-en-7-one, drima-5,8(9)-dien-7-one, and their 11,12-dibromo derivatives, potential intermediates for the synthesis of natural biologically active drimane sesquiterpenoids starting from norambreinolide. The key intermediate of the above drimane compounds is methyl 7-oxo-11-homodrim-8(9)-en-12-oate, prepared by electrochemical oxidation of a mixture of isomeric methyl bicyclohomofamesenoates obtained from norambreinolide.

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.
