Isoquinoline reacts smoothly with aroylnitromethanes in the presence of dialkyl acetylenedicarboxylates and dibenzoylacetylene to produce pyrrolo[2,1,a]isoquinolines in good yields. Quinoline and benzothiazole also react in a similar way. Pyridine and N-methylimidazole catalyze the reaction between nitromethane derivatives with electron-deficient acetylenes to produce highly functionalized isoxazoles. (C) 2009 Elsevier Ltd.
