  Synthesis and antiplasmodial activity of some 1-azabenzanthrone derivatives

  摘要：

  Some synthetic 1-azabenzanthrones (7H-dibenzo[de,h]quinolin-7-ones) are weakly to moderately cytotoxic, suggesting that they might also show antiparasitic activity. We have now tested a small collection of these compounds in vitro against a chloroquine-resistant Plasmodium falciparum strain, comparing their cytotoxicity against normal human fibroblasts. Our results indicate that 5-methoxy-1-azabenzanthrone and its 2,3-dihydro analogue have low micromolar antiplasmodial activities and showed more than 10-fold selectivity against the parasite, indicating that the dihydro compound, in particular, might serve as a lead compound for further development.

  Give me an H! Give me another H! The first general and highly enantioselective Ru‐catalyzed transfer hydrogenation of a wide range of 1‐aryl‐substituted 1,2,3,4‐dihydroisoquinolines is described. This atom‐economic reaction proceeds under mild conditions, allowing rapid access to the corresponding biologically relevant 1‐aryl‐tetrahydroisoquinoline derivatives, in high yields and enantioselectivities

  The reaction between 1-aryl-3,4-dihydroisoquinolines and monocyclic anhydrides was studied for the first time. The method is the first one-step route to previously unknown angularly-aryl substituted racemic [1,4]thiazino[3,4-a]isoquinoline derivatives with trans configuration. It was found that electron-withdrawing substituents in the p-position of the aryl group in the starting 3,4-dihydroisoquinoline

  Transfer hydrogenation using the Noyori catalyst 5-Ts is effective for the enantioselective hydrogenation of imines containing fully substituted nitrogen groups (12 or 13). Analogues such as Ile could not be reduced in practical yield, apparently due to product inhibition of the catalyst. Asymmetric transfer hydrogenation of the aniline imine 8a was possible, but required. impractical purity levels for the substrate, and the nitro analogue 7 could not be reduced efficiently. The best results were Obtained with the bromophenyl imine 20, In the case of 20b, the product 21b was formed with 98.7% ee, and the material could be upgraded to >99% ee by crystallization of the hydrochloride salt. Reaction of 21b with NH3 or MeNH2 in the presence of Cu/CuCl gave the chiral anilines 10b or 23b. The latter substance is comparable to the commercially available 1 as a chiral proton donor fog amide enolates and provides access to the hitherto unavailable enantiomeric series.
