A novel series of unsymmetrical C-N linked bis heterocycles bearing quinazolinone and acridinedione
skeletons have been synthesized in an acid promoted one pot multicomponent reaction. A blend of
6-aminoquinazolin-4-(3H)-one, aromatic aldehydes and cyclohexane-1,3-dione in a simple and efficient
condensation-cyclization reaction using hydrochloric acid in catalytic amount as catalyst afforded
unsymmetrical bis hybrids in good to excellent yields. Multiheterocyclic hybrid compounds were also
synthesized using heterocyclic ring containing aldehyde in three component reaction. The synthesized
quinazolinone-acridindione hybrids were characterized using spectroscopic techniques such as a IR,
1H NMR, 13C NMR, ESI-mass and HRMS.
一种新型不对称的C-N连接的双杂环化合物系列,含有喹唑啉酮和蒽醌酮骨架,已经在酸促进的一锅多组分反应中合成。在简单高效的缩合-环化反应中,将6-氨基喹唑啉-4-(3H)-酮、芳香醛和环己烷-1,3-二酮混合,使用催化量的盐酸催化剂,可以得到良好至优异的收率不对称双杂交物。多杂环杂交化合物也可以使用含有杂环环的醛在三组分反应中合成。合成的喹唑啉酮-蒽醌酮杂交化合物使用红外光谱、1H NMR、13C NMR、ESI-质谱和HRMS等光谱技术进行表征。
