Pre-clinical evaluation of cinobufotalin as a potential anti-l

Insights into the gold-catalyzed propargyl ester rearrangement/tandem cyclization sequence: radical versus gold catalysis-Myers-Saito- versus Schmittel-type cyclization. However, significant racemization was observed for malathion, phenthoate and fenpropathrin in methanol, ethanol and water, but not in n-hexane, isopropanol, acetone or methylene chloride.
