  摘要：

  The cycloaddition reaction of 3,6,9-tfihydrocyclohepta[c][1,2]dithiin (5), prepared from 3,4-bis(bromomethyl)-1,3,5-cycloheptatriene (3) in two steps, with 3,4-dimethylene-1,5-cycloheptadiene (6) in the presence of boron trifluoride-etherate gave 3,6,8,11,16-hexahydrodicyclohepta[c,h][1,6]dithiecin (2). The temperature-dependent NMR study indicated that 2 possesses the fluxional tetrahydrodithiecin moiety in solution at room temperature. The X-Ray crystal structure analysis showed that 2 has an S-letter shape which was supported as the most stable conformer by DFT molecular orbital calculations.
