Highly efficient and enantioselective hydrosilylation of aromatic alkenes catalyzed by the chiral rhodium acetate complexes with the bis(oxazolinyl)phenyl ligands has been reported that afforded chiral silane derivatives with up to 99% ee. [ABSTRACT FROM AUTHOR]

A 47-year-old woman with aspirin-exacerbated respiratory disease visited our hospital complaining of persistent chest pain that manifested in the evenings and early mornings. Holter monitoring revealed ST elevation during chest pain and coronary angiography showed coronary vasospasm, which led to the diagnosis of variant angina. Chest pain persisted despite administration of a coronary vasodilator. The patient experienced an increase in peripheral blood eosinophils during the clinical course and received prednisolone for the same, which resulted in the resolution of her chest pain. Prednisolone was therefore seen to be effective for treating variant angina that manifested as a non-respiratory tract symptom of aspirin-exacerbated respiratory disease.
