Here we report the design and synthesis of spiro[pyrrolidine-3,3′-oxindole] derivatives representing a novel scaffold of 5-HT7 receptor ligands. The synthesized analogues were validated as low nanomolar ligands showing selectivity in a panel of

Synthesis of piperazinyl-substituted oxazolopyridine and benzoxazole was achieved in three steps starting from aminophenol and carbon disulfide. Condensation of aminophenols with carbon disulfide in ethanol using potassium hydroxide as catalyst gave the required benzoxazole thiol in one step. Treatment of the thiol with piperazine and substituted piperazine derivatives in toluene furnished the titled compounds in good yield. We introduced halogen substitution in the pendant arm of the piperazine derivatives for versatile functionalization. We report the synthesis and characterization of these compounds using high resolution NMR techniques.

The synthesis of a series of substituted arylpiperazines linked to a 2-(pyridin-3-yl)-1H-benzo[d] imidazole scaffold through an alkylic linker is reported. The novel 1-(2-(4-arylpiperazin-1-yl) alkyl)-2-(pyridin-3-yl)-1H- benzimidazole derivatives are structurally related to the anti-HIV-1 drug Delavirdine and belong to the bis(heteroaryl)piperazines family (BHAPs), a well known HIV-1 reverse transcriptase inhibitors group.
