  摘要：

  5-Benzyl-2,3,5-trichloro-4.4-dimethoxycyclopent-2-en-1-one and 2-benzyl-2,4,5-trichlorocyclopent-4-ene-1,3-dione were Subjected to dehydrochlorination by the action of 1,4-diazabicyclo[2.2.2] octane, selective dechlorination at C-5 by the action of CrCl2, and Ad(N)E replacement of the chlorine atom at C-3 by the action of secondary amines. The reduction of 2-benzyl-2,4-dichloro-5-morpholinocyclopent-4-ene-1,3-dione with sodium tetrahydridoborate in methanol and ethanol gave different products.
