迫切需要开发针对野生型和D486N突变型F蛋白的有效呼吸道合胞病毒(RSV)融合糖蛋白(F蛋白)抑制剂。我们最近报道了一个15元的大环吡唑并[1,5- a ]嘧啶衍生物4,它不仅针对野生型,而且针对D486N突变F蛋白均表现出强大的抗RSV活性。但是,NMR研究表明15元衍生物4以阻转异构体的混合物形式存在。对苯甲酰基部分的2-位和吡唑并[1,5- a ]嘧啶支架的7位之间的连接子部分的优化研究确定了16元衍生物42c酰胺接头显示出快速阻转异构体。吡唑并[1,5- a ]嘧啶支架的5-位和苯甲酰基部分的5-位的随后优化导致发现了用于治疗RSV感染的有效临床候选物60b。

of amino esters is explored, and the first catalytic Michaeladdition of α-amino esters is demonstrated. These studies indicate that the acidity of the αC–H is the primary factor determining reactivity. Thus, polyfluorophenylglycine amino esters yield novel α-amino esters in the presence of a catalytic amount of a guanidine-derived base and Michael acceptors. Reactivity requires an acidic N–H, which
