‐chromene‐3‐carbaldehyde by heterogeneous catalysis
Chromenopyridines are an important class of compound because of their diverse biological activities. In the present work, we have developed convenient route for the synthesis of chromeno[4,3-b] pyridine derivatives (3a–e, 5a–e, and 7a–d) by Friedlander condensation of 4-amino-2-oxo-2H-chromene-3-carbaldehyde with various activemethylenecompounds. We have used mixed metal oxide catalyst such as nanomaterial
Chromenopyridines 是一类重要的化合物,因为它们具有多种生物活性。在目前的工作中,我们已经开发了便利的途径用于合成色烯并[4,3-的b ]吡啶衍生物(3a中- ë,5A - ë,和图7a - d由4-氨基-2-氧代的弗里德兰德缩合) 2小时-色烯-3-甲醛与各种活性亚甲基化合物。我们使用了混合金属氧化物催化剂,如纳米材料钛酸锌。反应是针对各种溶剂体系进行的,我们也改变了催化剂的浓度。就收率和反应速率而言,2-丙醇/水溶剂体系和5 mol%催化剂浓度是最佳的。合成化合物的结构经1 H NMR、13 C NMR、质谱和元素分析确证。
