Pyrrolizidine alkaloids from seven wild-growing Senecio species in Serbia and Montenegro / Pirolizidinski alkaloidi iz sedam samoniklih biljnih vrsta roda Senecio koje rastu u Srbiji i Crnoj Gori
(Serbian Chemical Society, 2009)
The genus Senecio (family Asteraceae) is one of the largest in the world. It comprises about 1100 species which are the rich source of pyrrolizidine alkaloids. Plants containing pyrrolizidine alkaloids are among the most ...
NaY zeolite: A useful catalyst for nitrile hydrolysis
(Molecular Diversity Preservation International, Basel, 2000)
The NaY zeolite catalysed hydrolysis of nitriles to primary amides is reported. It is found that aryl nitriles with strong electron-withdrawing substituents and cyanopyridines are readily hydrolysed in the water suspension, ...
