翻譯摘要
|
|
| 本文以環(huán)己酮、丙二腈與硫磺為原料合成了2-氨基-3-氰基-4,5,6,7-四氫-苯并噻吩,產(chǎn)率為91%。再與三氟乙酸和三氯氧磷反應(yīng)合成了關(guān)鍵中間體4-氯-2-三氟甲基-5,6,7,8-四氫苯并[4,5]噻吩并[2,3-d]嘧啶,產(chǎn)率為70%。最后與2-氨基-1,3,4-噻二唑類衍生物反應(yīng),合成了3個(gè)未見(jiàn)文獻(xiàn)報(bào)道的目標(biāo)化合物。目標(biāo)化合物的結(jié)構(gòu)經(jīng)IR、MS予以表征。 |

| Synthesised by cyclohexanone, malononitrile and sulfur with a yield of 91%,2 - amino-3 - cyano-4,5,6,7 - tetrahydro - benzothiophene was then to form the key intermediate of 4 - chloro-2 - (trifluoromethyl) -5,6,7,8 - tetrahydro-benzo [4,5] thieno [2,3 - -d] pyrimidine by reacting with trifluoroacetic acid and phosphorus oxychloride synthesized with 70% yield and, finally,the three unreported compound with 2 - amino-1, 3,4 - thiadiazole derivatives. The structure of the target compounds were characterized by IR and MS . |
