Lu, Tong published the artcileDesign and synthesis of C-ring quinoxaline-substituted sinomenine 1,2,3-triazole derivatives via click reactions, Related Products of chlorides-buliding-blocks, the publication is Journal of Chemical Research (2020), 44(11-12), 699-704, database is CAplus.
The synthesis of C-ring quinoxaline-substituted sinomenine 1,2,3-triazole derivatives at the 4-OH via click reactions was accomplished, and a total of 16 novel sinomenine double N-heterocyclic derivatives are obtained in 74%-95% yields. The C-ring is first transformed into a 1,2-diketone structure under the action of hydrochloric acid, and then reacted with o-phenylenediamine to obtain a C-ring quinoxaline-substituted structure. The 4-OH of sinomenine reacted with chloropropyne to give an alkynyl sinomenine, and then reacts with sodium azide and various benzyl chlorides to give the target compounds All the synthesized derivatives were characterized by Fourier-transform IR spectrometry, high resolution mass spectrometry, 1H NMR, and 13C NMR spectroscopy.
