1′,5-Dinitro-2′-phenyl-2′,3′,5′,6′,7′,7a’-hexa­hydro­spiro­[indoline-3,3′-1′H-pyrrolizin]-2-one

In the title cyclo-adduct, C(20)H(18)N(4)O(5), the rings of the pyrrolizine system adopt envelope conformations. A centrosymmetric dimer is formed via inter-molecular N-H⋯O hydrogen bonds between the indolinone rings.

3-Cyclo­hexyl­sulfan­yl-2-(4-methyl­phen­yl)-5,7-dinitro-1H-indole

In the title compound, C(21)H(21)N(3)O(4)S, the cyclo-hexane ring adopts a chair conformation. The nitro and methyl-phenyl groups are all coplanar with the indole ring system. Intra-molecular N-H⋯O and C-H⋯S hydrogen bonds generate S(6) ring motifs. The mol-ecules form R(2) (2)(20) centrosymmetric dimers via inter-molecular C-H⋯O hydrogen bonds. A short O⋯O contact [2.842 (2) Å] is observed in ...

Synthesis and Leishmanicidal Activity of 1-[5-(5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl]-4-benzoylepiperazines

A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...
