A concise, stereocontrolled, and practical synthesis of a neuraminidase inhibitor consisting of a highly functionalized D-proline scaffold is described. Key features involve a stereocontrolled addition of a propiolate ester to a chiral nonracemic nitrone derived originally from D-serine and the manipulation of acyclic and cyclic motifs en route to the target in 12.8% overall yield over 22 steps. Several
描述了由高度功能化的 D-脯氨酸支架组成的神经氨酸酶抑制剂的简洁、立体控制和实用的合成。主要特征包括将丙炔酸酯立体控制添加到最初衍生自 D-丝氨酸的手性非外消旋硝酮中,以及在通往目标的途中以 12.8% 的总产率在 22 个步骤中操纵无环和环状基序。几种结晶中间体适用于单晶 X 射线分析。
