This invention relates to a group of trisubstituted and tetrasubstituted pteridine derivatives, their pharmaceutically acceptable salts, N-oxides, solvates, dihydro- and tetrahydroderivatives and enantiomers, possessing unexpectedly desirable pharmaceutical properties, in particular which are highly active immunosuppressive agents, and as such are useful in the treatment in transplant rejection and/or in the treatment of certain inflammatory diseases. These compounds are also useful in preventing or treating cardiovascular disorders, allergic conditions, disorders of the central nervous system and cell proliferative disorders.

A K2S2O8-promoted oxidative tandem cyclization of primary alcohols with 2-aminobenzamides to synthesize quinazolinones was successfully achieved under undivided electrolytic conditions without a transition metal and base. The key feature of this protocol is the utilization of K2S2O8 as an inexpensive and easy-to-handle radical surrogate that can effectively promote the reaction via a simple procedure
AK 2 S 2 O 8促进了伯醇与2-氨基苯甲酰胺的氧化串联环化以合成喹唑啉酮,在没有过渡金属和碱的不分电解条件下成功实现。该协议的主要特点是利用 K 2 S 2 O 8作为一种廉价且易于处理的自由基替代物,可以通过简单的程序有效地促进反应,从而通过形成氮杂环在恒定电流下以一锅法在室温下直接氧化环化。由于使用了连续流动的电化学装置,这种绿色、温和、实用的电合成具有高效率和优异的官能团耐受性,并且易于放大。

green and sustainable chemistry for their synthesis. Herein, using I2 in coordination with electrochemical synthesis induced a C–H oxidation reaction which is reported when using water as the environmentally friendly solvent to access a broad range of quinazolinones at roomtemperature. The reaction mechanism strongly showed that I2 cooperates electrochemically promoted the oxidation of alcohols, then
开发在水性介质中使用生物相容性催化剂合成喹唑啉酮的方案将有助于解决使用绿色和可持续化学合成它们的困难。在此,使用 I 2与电化学合成配合会引起 C-H 氧化反应,据报道,当使用水作为环境友好溶剂在室温下获得广泛的喹唑啉酮时。反应机理有力地表明,I 2协同电化学促进醇的氧化,然后有效地将酰胺环化为各种喹唑啉酮。
