, (2019)
As a continuation of our efforts to discover and develop “me-better” active molecules, in this study, a series of novel isoxazole-amide derivatives containing an acylhydrazone moiety were synthesized and evaluated for their antiviral activities against tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV). Antiviral bioassays indicated that some of the target compounds exhibited better in vivo antiviral activities against TMV and CMV than those of Ningnanmycin (NNM). Especially, the compound 7t exhibited the best curative, protection, and inactivation activities against TMV and CMV which were superior to those of NNM. Meanwhile, our present work also revealed that compound 7t could enhance the defense-related enzyme activity and increase the chlorophyll content in tobacco leaves to induce resistance and enhance plant tolerance to TMV infection.

Synthesis of 1,2,3-triazole substituted isoxazoles via copper (I) catalyzed cycloaddition

The synthesis of a series of 3,5-disubstituted isoxazole-4-carboxylic esters containing N-substituted 1,2,3-triazoles (V) starting from various benzaldehydes (I) is reported. Benzaldehydes undergo oximation with hydroxylamine hydrosulfate. Later, chlorination followed by condensation with methylacetoacetate and the hydrolysis of the resulting ester afforded respective carboxylic acid (II), which on chlorination with PCl5 gave the corresponding acid chlorides (III). The coraboxylic acid chlorides (III) on propargylation gave propargylic esters (IV) and these on click reaction gave the title compounds (V).
