摘要
以2-氨基四氢环戊二烯并[4,5]噻吩-3-甲酸乙酯为原料,采用有别于文献报道的合成方法,经3-苯基-2-巯基四氢环戊二烯并[4,5]噻吩并[2,3-d]嘧啶-4-酮中间体,高产率的合成了未见文献报道的3-苯基四氢环戊二烯并[4,5]噻吩并[2,3-d]嘧啶-4-酮七乙酰乳糖硫苷.
The title compound 3-phenyl-2,3,6,7-tetrahydro-lH-cyclopenta [4,5 ] thieno [ 2,3-d] pryrimidine-4 （5 H）-one was synthesized from the started material ethyl 2-amino-5,6-dihydro-4H-cyelopenta[-h]thiophene-3- carboxylate, through the 3-phenyl-2-thioxo-2,3,6,7-tetrahydro-lH-cyelopenta[4,5] thieno[2,3-d]pryrimidine- 4（5H）-one intermediate in good yield.
