| Abstract: | 1,2,3,4-Tetrahydro-2,6-dimethyldibenzothiophene(3) was prepared by coupling of mixture of 2-bromo-3-methyl-cyclohexanone and 2-bromo-5-methyl-cyclohexanone with 2-methylbenzenethiol,followed by cyclization and purification.1,2,3,4,4a,9b-Hexahydro-2,6-dimethyldibenzothiophene(4) was synthesized by reduction of 3 with Zn in the presence of trifluoroacetic acid.The structures of 3 and 4 were confirmed by 1H NMR,13C NMR and GC-MS. |
