of acylketene precursors through extrusion of nitrogen gas is reported. Key to the development of a suitable continuous protocol is the balance of reaction concentration against pressure in the flow reactor. The resulting process enables access to intercepted acylketene scaffolds using volatile amine nucleophiles and has been demonstrated on the gram scale. Thermal gravimetric analysis was used to
报道了一种通过挤出氮气产生和使用酰基乙烯酮前体的流动化学工艺。开发合适的连续方案的关键是反应浓度与流动反应器中压力的平衡。由此产生的过程能够使用挥发性胺亲核试剂获得拦截的酰基烯酮支架,并且已经在克级上得到证明。热重分析用于指导各种酰基乙烯酮前体的反应器盘管的温度设定点。证明了两种反应性中间体(均来自氮挤压)的同时产生和反应。
