[reaction: see text] A novel, microwave-enhanced six-step synthesis was devised for the synthesis of N-shifted buflavine analogues. Microwave-enhanced Suzuki-Miyaura cross-coupling and ring-closing metathesis reactions were used as the key steps. Microwave irradiation was found to enhance the ring-closing metathesis reaction to generate the otherwise difficultly obtainable medium-sized ring system of the target
[反应:见正文]设计了一种新颖的微波增强六步合成法,用于合成N移位的牛黄素类似物。微波增强的Suzuki-Miyaura交叉偶联和闭环易位反应被用作关键步骤。发现微波辐射增强了闭环复分解反应,以生成原本难以获得的目标分子的中等大小的环系统。
