The preparation of the title compounds (Z)- and (E)-1, which are synthetic substitutes for the unstable bis(phenylsulfonyl) acetylene and key reagents for the asymmetric preparation of polycyclic ketones, has been revisited and improved. Starting from inexpensive materials such as trichloroethylene, thiophenol, and hydrogen peroxide, (Z)- and (E)-1 are selectively obtained in multigram quantity in
对标题化合物 (Z)- 和 (E)-1 的制备进行了重新审视和改进,它们是不稳定的双(苯磺酰基)乙炔的合成替代品和不对称制备多环酮的关键试剂。从三氯乙烯、苯硫酚和过氧化氢等廉价材料开始,(Z)- 和 (E)-1 以 52% 的总产率以多克的数量选择性地获得。
