described via regioselective 1,3-dipolar cycloaddition reactions of 3-(dimethylamino)-1-(pyridin-4- yl)prop-2-en-1-one (2) with nitrilimines 4a-h to afford the corresponding pyrazole derivatives 6a-h. Hydrazinolysis of 6a-c,e-f yielded the respective pyrazolopyridazines 7a-f. The enaminone 2 reacts also with 6-aminothiouracil (8) to yielded thione 9. The reaction of 9 with hydrazonoylchlorides 3 yielded
The herbicidalactivity of 3-cyanopyridin-2-yl phosphates, which were designed according to the idea of a mechanism-based inactivator, is probably related to a phosphatase.
