- Synthesis of some new pyrazole and pyrazolopyrimidine derivatives [1]
-
A series of pyrazolo [3,4-d] pyrimidine, pyrazolo [1,5-a] pyrimidine, and pyrazolyl triazoles have been prepared via reaction of ethyl 5-amino-3-phenylpyrazole-4-carboxylate with isothiocyanic esters, α,β-unsaturated nitriles, and some active methylene re

-
Polarized ethylenes having both electron-donating (an amino or a methylthio group) and electron-accepting (cyano, carbamoyl, methyl ester) groups on the adjacent two olefinic carbon atoms were prepared by the condensation of S-alkylthioamidinium salts or
