A two-step solution phase synthesis employing a double UDC (Ugi/Deprotect/Cyclize) strategy has been utilized to obtain fused 6,7,6,6-quinoxalinone-benzodiazepines and 6,7,7,6-bis-benzodiazepines. Optimization of the methodology to produce these tetracyclic scaffolds was enabled by microwave irradiation, incorporation of trifluoroethanol as solvent, and the use of the convertible isocyanide, 4-tert-butyl
采用双 UDC(Ugi/脱保护/环化)策略的两步液相合成已被用于获得融合的 6,7,6,6-喹喔啉酮-苯二氮卓类和 6,7,7,6-双-苯二氮卓类。通过微波辐射、加入三氟乙醇作为溶剂以及使用可转化的异氰化物 4-叔丁基环己烯-1-基异氰化物来优化生产这些四环支架的方法。
