  Conversion of 2-Thioxo-2,3-dihydroquinazolin-4(1H)-ones to N(3)-Unsubstituted 2-(Het)Arylquinazolin-4(3H)-ones by Copper-Mediated Pd-Catalysed Cross-Coupling Reactions

  摘要：

  With the purpose of searching for new heterocyclic building blocks, a new method to access N(3)-unsubstituted 2-(het)arylquinazolin-4(3H)-ones from 2-thioxo-2,3-dihydroquinazolin-4(1H)-one derivatives was developed. The synthetic protocol was based on the copper-mediated palladium-catalysed cross-coupling reactions of 2-thioxo-2,3-dihydroquinazolin-4(1H)-ones with (het)arylstannanes or their S-benzylated derivatives with (het)arylboronic acids, using CuBr center dot Me2S and CuMeSal as promoters, respectively. A similar transformation was applied for the preparation of 2-aryl[ 1]benzothieno[3,2-d]pyrimidin-4(3H)-ones.

  NLRP3 inflammasome is an important therapeutic target for a number of human diseases. Herein, computationally designed series of quinazolin-4(3H)-ones were synthesized using iodine-catalyzed coupling of arylalkynes (or styrenes) with O-aminobenzamides. The key event in this transformation involves the oxidative cleavage of the C–C triple/double bond and the release of formaldehyde. The reaction relies

  NLRP3炎性小体是许多人类疾病的重要治疗靶标。本文中，使用碘催化的芳基炔烃（或苯乙烯）与O-氨基苯甲酰胺的偶联反应，合成了一系列计算设计的喹唑啉4（3 H）-1 。此转变的关键事件涉及C–C三键/双键的氧化裂解和甲醛的释放。该反应取决于在无金属条件下C–N键的形成以及C–C键的裂解。硝基取代的喹唑啉-4（3 H）-1 2k通过抑制从ATP刺激的J774A.1细胞中释放的IL-1β抑制NLRP3炎性小体（IC 50 5μM）。

  aminobenzamides and in-situ generated aldehydes. Visible light was found to play a dual role: first oxidizes the alcohol to the aldehyde and then facilitates its cyclization with o-substituted aniline. Furthermore, alcohols are perfect alternatives to aldehydes because they are greener, more available, more economical, more stable, and less toxic than aldehydes. The first reaction step continuously

  A new strategy for the direct synthesis of quinazolinones from o‐aminobenzonitriles was proposed and accomplished. In the presence of [Cp*IrCl2]2 (Cp*=pentamethylcyclopentadienyl), a variety of desirable products was obtained easily through the one‐pot sequential selective hydration/condensation/acceptorless dehydrogenation. This protocol is highly attractive because it uses readily available starting
