They are neo coramandaline <b>1</b>, a new pyrrolizidine ester alkaloid and echinatine <b>3</b>. Neo coramandaline is formulated as 9-O-(-)viridifloryl laburnine on the basis of spectroscopic measurements and hydrolysis.

Compounds <b>4a-p</b> have been found to be bactericidal against <i>S. aureus </i>and <i>S. typhi </i>while compound <b>4n</b> shows fungicidal activity against <i>T. mentagrophytes </i>and <i>T.rubrum.</i> Page(s): 76-79 2000-01-01T00:00:00Z http://nopr.niscpr.res.in/handle/123456789/22468 Title: Oxidative transformation of alcohols and oximes to carbonyl compounds by quinolinium fluorochromate (QFC) Authors: Rajkumar, G Abraham; Arabindoo, Banumathi; Murugesan, V Abstract: Oxidation of selected alcohols and oximes to the corresponding carbonyl compounds has been achieved with quinolinium fluorochromate (QFC) in dichloromethane solvent under reflux conditions. The oxidation reactions have been found to be smooth and gave the products in good yield.
