The invention relates to organic compounds which have interesting pharmaceutical properties. In particular, the compounds are useful in the treatment and/or prevention of infections such as those caused by
Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, Plasmodium ovale, Trypanosoma cruzi
and parasites of the
Leishmania
genus such as, for example,
Leishmania donovani
. The invention also relates to pharmaceutical compositions containing the compounds, as well as processes for their preparation.

Racemic spiroazepineindole (1) was identified from a phenotypic screen on wild type Plasmodium falciparum with an in vitro IC(50) of 90 nM. Structure-activity relationships for the optimization of 1 to compound 20a (IC(50) = 0.2 nM) including the identification of the active 1R,3S enantiomer and elimination of metabolic liabilities is presented. Improvement of the pharmacokinetic profile of the series translated
We describe an unprecedented dual C-H functionalization of indolin-2-one via an oxidative C(sp3)-H/N-H/X-H (X = N, C, S) cross-coupling protocol, which is catalyzed by a simple iron salt under mild and ligand-free conditions and employs air (molecular oxygen) as the terminal oxidant. This method is readily applicable for the construction of tetrasubstituted carbon centers from methylenes and provides

A recyclablecatalyst, β-cyclodextrin-SO3H in aqueous medium was used effectively for the synthesis of spiroindolones (tetrahydrospiro-β-carbolines as well as tetrahydrospiro-γ-carbolines) in a Pictet-Spengler spirocyclisation. The products were obtained in good yield in an environmental friendly procedure.
