  Synthesis of 4 H ‐chromene‐isoxazole hybrids via ortho ‐hydroxy directing cyclization of isoxazole‐styrenes and Michael addition of imino‐chromenes in aqueous medium

  摘要：

  AbstractA green, efficient, and one‐pot method synthesis of functionalized 4H‐chromene‐isoxazole hybrids is reported via o‐hydroxy group directing cyclization of isoxazole‐styrenes and Michael addition of 3,5‐dimethyl‐4‐nitroisoxazole on 2‐imino‐2H‐chromene‐3‐carbonitrile (independent methods). The developed methodology was further extended for nitromethane, malononitrile, and alkylcyanoacetates as Michael donors.

  A facile, one-pot three-component protocol for the synthesis of 2-amino-4H-chromene derivatives has been demonstrated using Bael Fruit Extract (BFE) as a natural catalyst in a green reaction medium. This method offers a mild, efficient and highly economical protocol since the reaction proceeds in natural BFE-catalyst at room temperature under aerobic conditions with a very short reaction time (30 min)

  使用Bael水果提取物（BFE）作为绿色反应介质中的天然催化剂，已经证明了用于合成2-氨基-4 H-色烯衍生物的一种简便的一锅三组分方案。该方法提供了温和，有效和高度经济的方案，因为该反应在需氧条件下于室温下在天然BFE催化剂中进行，在配体/外部催化剂/无外部助催化剂的条件下，反应时间非常短（30分钟），因此，它是现有协议的绿色环保选择。通过热处理，然后水提取Aegle marmelos（bael）果皮的外皮得到催化剂。还发现它是清洁的，高产率的并且具有大规模合成的能力。

  Résumé Diethylamine has been demonstrated to be an efficient organocatalyst in the diastereoselective synthesis of Bcl-2 protein antagonist (HA-14-1) and of its structural analogues by one-pot condensation between salicylaldehyde and three different C–H acids, viz. ethyl cyanoacetate, phenylsulfonyl acetonitrile, and malononitrile. Easy commercial availability of the catalyst at extremely low cost and avoidance of conventional work-up as well as purification procedures qualifies this scalable protocol for a “near-ideal synthesis”.
