✦ Synopsis
Heterocyclization of 4-Trifluoroacetyl-2,3-dihydropyrroles with Hydrazines and Amidines: A New Access to Trifluoromethylated Pyrazoles and Pyrimidines Bearing a β-Aminoethyl Side Chain. -Condensation of dihydropyrrole (I) with hydrazines opens a new access to trifluoromethylated pyrazoles (III)/(IV). Similarly, condensation with amidines gives the corresponding pyrimidines (VI). -(KAWASE, MASAMI;
