Asymmetrical oxidation was performed of menthone dithiolane obtained in 95-98% yield by condensation of menthone with 1,2-ethanedithiol in the presence of boron trifluoride etherate. 6-Isopropyl-9-methyl-1,4-dithiaspiro[4,5] decane-1,4-dioxide (yield 5-55%) and 6-isopropyl-9-methyl-1,4-dithiaspiro[ 4,5]-decane-1,1,4-trioxide (yield 65-70%) were synthesized. Chemical structures of compounds obtained were proved by XRD analysis, NMR and IR spectroscopy.
