N-Alkyl-N-(5-isothiazolyl)- and N-(Alkylisothiazolin-5-ylidene)- phenylacetamides. Synthesis and Biological Activity
摘要:
Treatment of 5-amino-4-chloro-3-methylisothiazole (3) with the acid chloride of [p-[(alpha,alpha,alpha-trifluoro-p-tolyl)oxy]phenyl]acetic acid (6) afforded the amide N-(4-chloro-3-methyl-5-isothiazolyl)-2-[p-[(alpha,alpha, alpha-trifluoro-p-tolyl)oxy]phenyl]acetamide (1), which was substituted with various alkyl groups in an effort to alleviate toxicity toward non-target organisms through a proinsecticide approach. Alkylations of 1 under a variety of reaction conditions afforded two major products which were derived from amide-nitrogen substitution, N-alkyl-N-(4-chloro-3- methyl-5-isothiazolyl)-2-[p-[(alpha,alpha,alpha-trifluoro-p-tolyl)oxy]phenyl]acetamides (a), and ring-nitrogen substitution, N-(2-alkyl-4-chloro-3-methyl-3-isothiazolin-5-ylidene)-2-[p- [(alpha,alpha,alpha-trifluoro-p-tolyl)oxy]phenyl] acetamides(8). Derivatives 7 and 8 were found to exhibit lessened toxicity to trout as well as insects, but, in general, efficacy toward insects was retained to a greater degree. In particular methoxymethyl, ethoxymethyl, ethyl, and ethyl-d(5) substituents demonstrated the best combination of insect efficacy and safening toward trout. Significantly different in vivo efficacies of the N-methyl and N-CD3 analogs suggest that 7 and 8 are proinsecticides requiring activation by dealkylation.

An efficient synthesis of the novelmicrotubuleinhibitor STA-5312 (3-[(4-cyanophenyl)methyl]-N-(3-methyl-5-isothiazolyl)-α-oxo-1-indolizineacetamide) was developed. A novel DMF/Me2SO4 directed regioselective synthesis of the 3-(4-cyanobenzoyl)-indolizine (4) was a critical transformation within the four-step process. Alternatively, a CuCl mediated synthesis of 3-(4-cyanobenzyl)indolizine (5) was also
