Abstract: | (1R,1′R,2S,4R)-1,7,7-Trimethylspirobicyclo2.2.1]heptane-2,2′-1,3]dithiolane] 1′-oxide, (1R,2S,3′R,4R)-1,7,7-trimethylspirobicyclo2.2.1]heptane-2,2′-1,3]dithiolane] 1′,1′,3′-trioxide, and (1R,4R)-1,7,7-trimethylspirobicyclo2.2.1]heptane-2,2′-1,3]dithiolane] 1′,1′,3′,3′-tetraoxide were synthesized by oxidation of
camphor ethylene dithioacetal with m-chloroperoxybenzoic acid at different substrate-tooxidant ratios. The structure of the products was proved by IR and NMR
spectroscopy and X-ray analysis. |
