2‐(Arylidene)cyanomethylbenzoxazoles have been prepared in water from benzoxazole‐2‐ylacetonitriles. Using multi‐component reactions, a variety of heterocycles containing benzoxazole and nitrile functionality has been prepared. J. Heterocyclic Chem., (2011).

The reaction of [RuCl2(p-cymene)](2) with benzoxazoleacetonitriles and NH4+BF4- in methanol leads to bidentate N,N'-benzoxazole-methoxyimine-ruthenium(II) complexes 7, corresponding to the addition of methanol to the ruthenium(II)-activated nitrile triple bond. The X-ray structure of a complex 7 shows equivalent Ru-N and slightly different C=N bond distances. The catalytic hydration of benzoxazolacetonitriles with [RuCl2(p-cymene)](2) in methanol/water leads to quantitative formation of corresponding amides under mild conditions.

microsomes and no hERG channel inhibition liability were identified and evaluated in vivo for pharmacokinetic properties. Mtb-mediated permeation and metabolism studies revealed that the carbamates were acting as prodrugs. Toward mechanism of action elucidation, selected compounds were tested in biology triage assays to assess their activity against known promiscuous targets. Taken together, these data suggest
