its biological activity, pharmacokinetic profile, and physical properties. As part of an ongoing effort to develop novel methods for methylation of small molecule drug candidates, a three-component coupling of aryliodides, O-benzoylamines, and methylboronic acid that proceeds via a Catellani-type mechanism has been developed. The methodology allows for the ortho-amination/ipso-methylation of aryl- and
将甲基结合到小分子中可对其生物学活性,药代动力学特征和物理性质产生深远影响。作为开发用于使小分子药物候选物甲基化的新方法的正在进行的工作的一部分,已经开发了通过卡泰拉尼型机制进行的芳基碘化物,O-苯甲酰胺和甲基硼酸的三组分偶联。该方法允许对邻-amination /本位的芳基-和heteroaryliodides与多种环状的-methylation ö -benzoylamines包括吡咯烷,哌啶,哌嗪,吗啉,吖庚因,二氮杂,并azocanes在一个单一的步骤。邻位的初步结果-methylation /本位-olefination Catellani型三偶合成分反应也被描述。
