Antimalarial drugs. 64. Synthesis and antimalarial properties of 1-imino derivatives of 7-chloro-3-substituted-3,4-dihydro-1,9(2H,10H)-acridinediones and related structures
摘要:
To improve upon the activity and properties of the 3-aryl-7-chloro-3,4-dihydro-1,9(2H,10H)-acridinediones, a variety of 1-[(alkylamino)alkylene]imino derivatives (3) were prepared and shown to be highly active antimalarial agents in both rodents and primates. Among structural modifications prepared, including N-10-alkyl and C2-substituted analogs, removal of the C-9 oxygen, and introduction of an imino side chain at C-9, the imines of the N-10-H acridinediones were the most active compounds obtained. The [3-(NN-dimethylamino)propyl]imino derivative of 7-chloro-3-(2,4-dichlorophenyl)-3,4-dihydro-1,9(2H,10H)-acridinedione (9aa) proved to be highly active in advanced studies in primates.

日期:——
Hypervalentiodoniumylides expeditiously generate carbenes which undergo domino intermolecular C–H activation followed by intramolecular condensation in the presence of N-methoxybenzamide as a starting material and a Rh(III)-catalyst to afford dihydrophenanthridines. KIE studies and DFT calculations were performed to substantiate the mechanistic pathway. To extend the synthetic utilisation, fluorescent
