The synthesis of 14 novelN-propargylicβ-enaminonesfrom the reaction of β-alkoxy vinyltrihalomethyl[carboxyethyl] ketones [R(3)C(O)CHC(R(1))OMe, where R(3)=CF(3), CCl(3), CO(2)Et and R(1)=Me, Et, Pr, Bu, i-Pent, CH(2)CH(2)CO(2)Me] with propargyl amines [R(2)NHCH(2)CCH, where R(2)=Pr, PhCH(2)] is reported. Yields, solvents and reaction times needed for reaction completion, by microwave irradiation
