(hFPPS). Analogs were prepared via cyclization of 2-(1-(trimethylsilyl)ethylidene)malononitrile to 2-amino-4-(trimethylsilyl)thiophene-3-carbonitrile in the presence of elemental sulfur. Direct ipso-iododesilylation of this intermediate led to selective iodination at Cβ of the sulfur atom in high efficiency. The synthetic protocols developed were used in the parallel synthesis of structurally diverse thieno[2
基于硫代嘧啶的双膦酸酯被鉴定为人法呢基焦磷酸合酶(hFPPS)的一类新型的含氮双膦酸酯(N-BP)抑制剂。在元素硫的存在下,通过将2-(1-(三甲基甲硅烷基)亚乙基)丙二腈环化成2-氨基-4-(三甲基甲硅烷基)噻吩-3-甲腈来制备类似物。引导本位该中间导致了选择性碘化中C的-iododesilylation β在高效率的硫原子的。所开发的合成方案被用于结构平行的hFPPS的基于硫杂[2,3 - d ]嘧啶-4-胺的双膦酸酯抑制剂的合成。
