  Natural Product Derived Antiprotozoal Agents: Synthesis, Biological Evaluation, and Structure–Activity Relationships of Novel Chromene and Chromane Derivatives

  摘要：

  Various natural products with the chromane and chromene scaffold exhibit high antiprotozoal activity. The natural product encecalin (7) served as key intermediate for the synthesis of different ethers 9, amides 11, and amines 12. The chromane analogues 14 and the phenols 15 were obtained by reductive amination of ketones 13 and 6, respectively. Angelate 3, ethers 9, and amides 11 did not show considerable antiprotozoal activity. However, the chromene and chromane derived amines 12, 14, and 15 revealed promising antiprotozoal activity and represent novel lead compounds. Whereas benzylamine 12a and a-methylbenzylamine 12g were active against P. falciparum with IC50 values in the range of chloroquine, the analogous phenols 15a and 15b were unexpectedly 10- to 25-fold more potent than chloroquine with selectivity indexes of 6760 and 1818, respectively. The phenylbutylamine 14d based on the chromane scaffold has promising activity against T. brucei rhodesiense and L. donovani.

  report a novel strategy for the design and construction of natural and natural product-like libraries based on the principle of privileged structures, a term originally introduced to describe structural motifs capable of interacting with a variety of unrelated molecular targets. The identification of such privileged structures in natural products is discussed, and subsequently the 2,2-dimethylbenzopyran

  An elegant synthesis of linear acetylchromenes, viz eupatoriochromene, methyleupatoriochromene (encecalin), evodionol and methlevodionol, has been achieved by blocking the reactive position position C-3 of the appropriate ketones with an iodo group, prenylation with 3-chloro-3-methylbut-1-yne and subsequent cyclisation. Regiospecific introduction of C-prenyl group in the less reactive C-5 has been

  A novel method of nuclear isoprenylation leading to the exclusive formation of 2,2-dimethylchromans has been achieved by the direct condensation of polyhydroxyacetophenones with isoprene in presence of phosphoric acid. Acetylchromans, thus obtained, are dehydrogenated with DDQ to given corresponding 2,2-dimethylchromenes. Using this method, synthesis of number of naturally occurring chromenes, viz

  Orientation in acylation reactions of 2,2-dimethyl-2H-chromenes was studied. Five acetylchromenes were obtained with two methods and six formylchromenes were obtained with a third method. Demethylation of four acyl-methoxy-substituted chromenes gave the corresponding acylchromenols. 2,2-Dimethyl-2H-chromene-6-carboxylic acid (anofinic acid) was also obtained by oxidation of 6-formylchromene.
