Fifteen N-propargylic β-enaminones were synthesized from the reaction of propargyl amines [4X-PhNHCH2C≡CH, where X = H, Me] and 4-alkoxy-1,1,1-trihalo[ethoxy]-3-alken-2-ones [RC(O)CH=C(R)OMe, where R = CF3, CCl3, CO2Et and R = Me, Et, Pr, Bu, i-Pent, CH2CH2CO2Me]. The methodology described herein proceeded smoothly and furnished the products in good to high yields (70-95%).
由炔丙胺[4X-PhNHCH2C≡CH,其中X = H,Me]和4-烷氧基-1,1,1-三卤代[乙氧基]-3-alken-2反应合成了15种N-炔丙基β-烯胺酮-ones [RC(O)CH=C(R)OMe,其中 R = CF3、CCl3、CO2Et 和 R = Me、Et、Pr、Bu、i-Pent、CH2CH2CO2Me]。本文描述的方法进行得很顺利,并以良好到高产率 (70-95%) 提供产品。
