摘要
建立了一种简捷、绿色合成多取代色酮并双环吡啶类化合物的合成方法.该方法是利用色酮-3-甲醛1与N-苄基硝基烯酮缩胺(NBNKAs,2)在乙醇中反应,一步合成色酮并双环吡啶化合物.通过直接抽滤得目标产物3,无需额外的后处理操作.该方法具有合成成本低,反应溶剂生物相容性好,反应条件温和,原子经济性,高产率(93~98%)及产物具有潜在的生物活性等显著优势.
A concise and environment friendly route for the synthesis of multisubstituted chromone-fused bicyclic pyridine compounds via one-step reaction of chromone-3-carboxaldehyde 1 and N-benzyl nitro ketene aminals(NBNKAs, 2) in ethanol media has been developed. The targeted compounds 3 can efficiently obtain by filter without extra post-treatment. The reaction is particularly attractive due to following features: low-cost and biocompatibility solvent, mild temperature, atom economy, high yields, and potential biological activity.
