  Synthesis of N-Heteropolycyclic Compounds Including Quinazolinone Skeleton Using Friedel–Crafts Alkylation

  摘要：

  A simple method to synthesize N-heteropolycyclic quinazolinones was developed including Knoevenagel condensation of quinazolines and aldehydes and Friedel-Craft alkylation as key steps. Knoevenagel reaction of 2-methyl-3-phenylquinazolin-4(3H)-one proceeded smoothly under a basic condition and subsequent Friedel-Craft alkylation with BrOnsted acid gave the N-heteropolycyclic quinazolinones in good yields. Furthermore, these new polycyclic compounds were converted into organic molecules having a long -conjugation system by treatment of 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) to utilize them as organic dyes.

• Metal and phosgene-free synthesis of 1H-quinazoline-2,4-diones by selenium-catalyzed carbonylation of o-nitrobenzamides

  were efficiently synthesized by selenium-catalyzed carbonylation of o-nitrobenzamides under relatively mild conditions. In situ-generated carbonyl selenide (SeCO) is proposed to initiate the catalytic carbonylation. Thus, a concise transition metal and phosgene-free synthetic route to potentially bioactive-substituted 1H-quinazoline-2,4-dione derivatives has been developed.

  在相对温和的条件下，通过硒催化邻硝基苯甲酰胺的羰基化反应，可以有效地合成1 H-喹唑啉-2,4-二酮。建议原位产生的羰基硒化物（SeCO）引发催化羰基化反应。因此，已经开发出一种简明的过渡金属和无光气的合成路线，可以潜在地被生物活性取代的1 H-喹唑啉-2,4-二酮衍生物。

  A novel approach for the synthesis of 2,3-diarylquinazolinones using iron as catalyst is described. Various 2-nitro-N-arylbenzamides reacted with benzylic alcohols to selectively give the corresponding products in the absence of external oxidant or reductant.
