Divergent total synthesis of the natural antimalarial marinoquinolines A, B, C, E and unnatural analogues
摘要:
A new synthetic route to marinoquinolines was developed, allowing the synthesis of several structurally related compounds from a common key intermediate. Four natural marinoquinolines (A, B. C and E) and nine unnatural new analogues were prepared by this strategy, which features a Heck-Matsuda reaction in pure water and the Pictet-Spengler reaction as key steps. (C) 2012 Elsevier Ltd.

AbstractModified synthesis and antitubercular activity of 4-substituted pyrrolo[2,3-c]quinolines are reported. Some of the compounds showed significant antitubercular activity, when compared to some of the existing antitubercular drugs. A compound with an imidazole moiety at position 4 shows the highest activity and least toxicity. Graphical abstract
