for the synthesis of 1,3-phenylene-bis[6-(2-thiouracil)] 4. Desulphurization of 4 gave the corresponding bis-uracil 6, which after silylation was N-1 alkylated with bis(allyoxy)methane using TMS-triflate as the catalyst or with chloromethyl ethyl ether to give the MKC-442 analogues 7 and 9. The amino-DABO and S-DABO derivatives 11, 12a,b and 14 were also synthesized. The anti-HIV-1 activity test showed
1,3-苯二乙腈与2-溴丁酸乙酯的锌有机金属试剂反应,得到1,3-亚苯基-双(乙酰乙酸酯)2,用作合成1,3-亚苯基-双[6]的起始原料-(2-硫尿嘧啶)] 4。对4进行脱硫得到相应的双尿嘧啶6,在甲硅烷基化后,使用TMS-三氟甲磺酸盐作为催化剂,用双(烯氧基)甲烷将N-1烷基化,或用氯甲基乙基醚烷基化,得到MKC-442类似物7和9。氨基-DABO和S-DABO衍生物11、12a,b和14也被合成了。抗HIV-1活性测试表明,当在所有情况下用1,3-亚苯基构建MKC-442类似物时,它们均具有抗HIV-1的活性。
