confirmed using X‐ray crystallography. In catalytic activity studies, complex 5 was found to be an effective catalyst in the hydrogen‐transfer reduction of α,β‐unsaturated carbonyl compounds into the corresponding saturated carbonyl compounds.
Design, synthesis and biological evaluation of 8-(2-amino-1-hydroxyethyl)-6-hydroxy-1,4-benzoxazine-3(4H)-one derivatives as potent β2-adrenoceptor agonists
β2-adrenoceptor agonists with an 8-(2-amino-1-hydroxyethyl)-6-hydroxy-1,4-benzoxazine-3(4H)-one moiety is presented. The stimulatory effects of the compounds on human β2-adrenoceptor and β1-adrenoceptor were characterized by a cell-based assay. Their smooth muscle relaxant activities were tested on isolated guinea pig trachea. Most of the compounds were found to be potent and selectiveagonists of the β2-adrenoceptor
Nickel-catalyzed electrochemical conjugate additions of substituted aryl bromides to activatedolefins under recently optimized reaction conditions are reported. Good to high yields were obtained, whatever the nature of substituents in the meta- and para-positions of the benzene ring. In the ortho-substituted series, yields were good with electron-donating substituents, but low with electron-withdrawing
