A novel heterogeneous combination of a formate reagent and palladium catalyst co-immobilized on a resin support has been developed and shown to be highly efficient and recyclable for transfer hydrogenation of alkenes, imines, nitroarenes and 1,2-dicarbonyl compounds.

hetaryl fragments were easily prepared from corresponding aldimines derived from commercially available aromatic aldehydes and anilines. 2-Furyl substituted anilines showed very good antifungal activities against dermatophytes, particularly against Trichophyton rubrum (MIC=3.12-6.25microg/mL). In addition, all active compounds, 45-47, 73, and 74, were tested for cytotoxic activities against breast (MCF-7)
Compounds having the formula
and pharmaceutically acceptable salts thereof wherein X is alkyl, Y is a single bond, -CH₂-, -C(O)-, -O-, -S- or -N(R⁸)- where R⁸ is hydrogen, alkyl, haloalkyl, aryl, arylalkyl, cycloalkyl or (cycloalkyl)alkyl, and R¹ to R⁷ are as defined herein. These compounds have potassium channel activating activity and are useful, therefore for example, as cardiovascular agents.
