By combining 2 chloropyridine, 1,3,4 thiadiazole and acylamide, three toxophoric moieties seven 2 [ N (1 methoxycarbonyl)ethyl N acyl]amino 5 [(2 chloropyrid) 4 yl] 1,3,4 thiadiazoles(8) were synthesized in seven step...By combining 2 chloropyridine, 1,3,4 thiadiazole and acylamide, three toxophoric moieties seven 2 [ N (1 methoxycarbonyl)ethyl N acyl]amino 5 [(2 chloropyrid) 4 yl] 1,3,4 thiadiazoles(8) were synthesized in seven steps. The preliminary biological activity tests show that the title compounds reveal a certain plant growth regulating effect as well as fungicidal activity.展开更多
