An undergraduate laboratory was developed as part of the Drugs for Neglected Diseases initiative’s Open Synthesis Network. This activity aimed to develop new compounds efficacious against visceral leishmaniasis. Students successfully synthesized, purified, and characterized ten different benzoxazole amides that were sent biological testing several protozoan parasites. Although all had poor L. d...

A simple and facile method for the preparation ofFe2+ supported on hydroxyapatite-core-shell-γ-Fe2O3 nanoparticles (γ-Fe2O3@HAp-Fe2+ NPs) as an environmentally friendly and recyclable green catalyst is described and used for the one-pot synthesis of benzimidazoles and benzoxazole derivatives via reactions between aromatic aldehyd...

Transient precursor states are often experimentally observed for molecules adsorbing on surfaces. However, such precursor states are typically rather short-lived, quickly yielding to more stable adsorption configurations. Here we employ first-principles calculations to systematically explore the interaction mechanism for benzene derivatives on metal surfaces, enabling us to selectively tune the...

A bis(benzoxazole) derivative with metal-chelating ligand (DPA), Zinhbo-1, exhibits a large fluorescence turn-on effect (up to 10-fold) upon zinc-binding. The metal chelation enables excited state intramolecular proton transfer (ESIPT), giving an additional emission band in the near-IR region (approximately 710 nm) with a large Stokes shift (ca. 230 nm).

In the title compound, C(14)H(11)ClN(2)O(2), the 2,3-dihydro-1,3-benzoxazole ring system is essentially planar [maximum deviation = 0.009 (2) Å] and makes a dihedral angle of 79.15 (7)° with the phenyl ring. Inter-molecular N-H⋯O and weak C-H⋯Cl hydrogen bonds occur in the crystal structure.
