The present invention refers to new compounds useful in the treatment of leishmaniasis and, more particularly, to a series of 5-6-5 triazole-phenyl-thiazole heterocycles capable of inhibiting both activity and dimerization of L. infantum TryR in enzymatic assays at low micromolar concentrations and endowed with potent in vitro activity against promastigote and amastigote forms of Leishmania which indicates a good permeability across the plasma membrane of the parasites.

Herein, we report an efficient synthetic method for polysubstituted pentafulvenes via palladium-catalyzed deacetylative [2+2+1] annulation of enones with alkynes. Aryl-, alkenyl-, and alkyl-substituted α,β-enones were suitable substrates, affording the pentafulvene products in moderate to good yields. This protocol shows excellent compatibility with sensitive halides, free hydroxyl groups, and heterocycles
