Synthesis of 8-Methyl-5-[(methylsulfanyl)methyl]-3-thiabicyclo[3.3.1]non-7-en-6-one and Its Extraction Ability for Gold(III)

An efficient one-pot procedure has been proposed for the synthesis of 8-methyl-5-[(methylsulfanyl) methyl]-3-thiabicyclo[3.3.1]non-7-en-6-one from accessible natural raw materials. A stable complex of the title compound with gold(III) has been obtained by the extraction method, and the mode of its coordination to the metal ion has been determined by IR and NMR spectroscopy.
