Synthesis and Biological Activity of New 2-{[6-Methyl-2-(pyrrolidin-1-yl)pyrimidin-4-yl]oxy}acetohydrazide Derivatives

详细

The reaction of 6-methyl-2-(pyrrolidin-1-yl)pyrimidin-4(3H)-one with methyl chloroacetate, followed by hydrazinolysis, gave 2-{[6-methyl-2-(pyrrolidin-1-yl)pyrimidin-4-yl]oxy}acetohydrazide, and the latter was used to obtain a series of new derivatives, including those containing a 1,2,4-triazole, 1,3,4-oxadiazole, or furan ring in addition to the pyrimidine fragment. Preliminary biological screening of the synthesized compounds revealed a pronounced plant growth stimulating effect at a level of 65–87% relative to heteroauxin.
