An efficient synthesis of O,O- di propyl (E)-2-[1-methyl 2-oxopropylidene]phosphorohydrazidothiolate (E) oxime and its analogues: A potential marine toxin

Gupta, Arvind K.,Dubey,Parashar,Kaushik

, p. 1892 - 1910 (2008)

An efficient method for the synthesis of Ptychodiscus brevis toxin O,O- di n-propyl (E)-2-[1-methyl 2-oxopropylidene]phosphorohydrazidothiolate (E) oxime (TG-1) and its analogues has been developed using thermally stable and recyclable silica gel and Na2SO4 as a condensing agent and water scavenger, respectively. The compounds were evaluated against fish Rasbora daniconius by determining the LC50 and LC90 values. The results of biological evaluation showed that these compounds have high degree of toxicity.
