insulin-like growth factor I receptor (IGF-IR) inhibitor AEW541 (1) is described. The key step in the synthesis is the cis-selective reductive amination of cyclobutanone, which sets up the desired 1,3-stereochemistry of the cyclobutane ring. The amino group thus generated is used as a handle to build the pyrrolopyrimidine ring. The final step resulting in 1 is accomplished by alkylation of in situ generated
描述了有效的胰岛素样生长因子I受体(IGF-1R)抑制剂AEW541(1)的有效合成。合成中的关键步骤是环丁酮的顺式-选择性还原胺化,它建立了所需的环丁烷环的1,3-立体化学。如此产生的氨基被用作构建吡咯并嘧啶环的手柄。通过用氮杂环丁烷原位产生的甲磺酸盐的烷基化来完成产生1的最后步骤。
