2‐alkylquinazolinones are key synthetic intermediates, but their preparation in high optical purity is challenging. Thus, a multicomponent procedure integrating anthranilic acids, N‐Boc‐amino acids, and amines in the presence of methanesulfonyl chloride, N‐methylimidazole, and copper(II) chloride was developed to mildly afford N‐Boc‐2‐alkylaminoquinazolin‐4(3H)‐ones with excellent preservation of enantiomeric
手性2-烷基喹唑啉酮是关键的合成中间体,但其高光学纯度的制备具有挑战性。因此,开发了一种在甲磺酰氯、 N-甲基咪唑和氯化铜(II)存在下整合邻氨基苯甲酸、 N -Boc-氨基酸和胺的多组分程序,以温和地提供N -Boc-2-烷基氨基喹唑啉-4( 3 H )-具有出色的对映体纯度保留 (>99% ee)。氯化铜(II)对于保持对映体纯度至关重要,并且反应组分结构变化具有良好的耐受性,从而形成一种高效的一体化程序,促进连续偶联、内酯化、氨解和环化,并获得良好的收率。该方法适用于快速组装用于合成高浓度喹唑啉酮类药物的四种关键中间体,包括几种 PI3K 抑制剂药物。

The invention relates to the preparation and use of new aminopyrimidine derivatives as drug candidates in free form or in pharmaceutically acceptable salt form and formulations thereof for the modulation of a disorder or disease which is mediated by the activity of the PI3K enzymes. The invention also provides pharmaceutically acceptable compositions comprising such compounds and methods of using the compositions in the treatment of disorders or diseases, such as disorders of immunity and inflammation in which PI3K enzymes play a role in leukocyte function, and hyperproliferative disorders associated with PI3K activity, including but not restricted to leukemias and solid tumors, in mammals, especially humans.
