  串联钯催化的尿素芳基化-分子内酯酰胺化：3-烷基化的2,4-喹唑啉二酮的区域选择性合成。

  摘要：

  邻卤代苯甲酸酯可与单烷基脲按串联钯催化的芳基化酯酰胺化顺序结合，以生成喹唑啉二酮产物。反应对于形成3-N-烷基异构体是区域选择性的。两个偶联配偶体的显着变化是可能的，从而允许合成各种取代的喹唑啉二酮，例如制备简单的不对称二烷基化天然产物。[反应：看文字]

  Abstract Two new 4-quinazolone alkaloids have been isolated from seed husks of Zanthoxylum arborescens . Based on their spectroscopic properties they have been assigned structures, 1-methyl-3-(2′-phenylethyl)-1H,3H-quinazoline-2,4-dione and 1-methyl-3-[2′-(4″-methoxyphenyl)ethyl]-1H,3H-quinazoline-2,4-dione. These structural assignments have been confirmed by synthesis. Skimmianine has been obtained

• Nickel-Catalyzed Synthesis of Quinazolinediones

  A nickel(0)-catalyzed method for the synthesis of quinazolinediones from isatoic anhydrides and isocyanates is described. High-throughput ligand screening revealed that XANTPHOS was the optimal ligand for this transformation. Subsequent optimization studies, supported by kinetic analysis, significantly expanded the reaction scope. The reaction exhibits a case of substrate inhibition kinetics with respect to the isocyanate. Preliminary results on an asymmetric synthesis of atropisomeric quinazolinediones are reported.
