We designed a robust and efficient greener synthetic protocol to access p-quinone fused 5-substituted-1,4-benzodiazepine scaffolds, a new molecular hybrid, through InCl3 mediated Pictet–Spengler type cycloannulation of 2-amino-3-arylamino-p-quinone and commercially prevalent aldehydes. This protocol would ease access to privileged redox-active p-quinone fused seven-membered frameworks that are difficult
我们设计了一种稳健且高效的绿色合成方案,通过 InCl 3介导的 Pictet-Spengler 型 2-amino-3-arylamino- p环化来获得对醌稠合 5-取代-1,4-苯二氮卓支架(一种新的分子杂合体)。 -醌和商业上流行的醛。该协议将简化对其他协议难以访问的特权氧化还原活性对醌稠合七元框架的访问,并将在
