All at once: Microwave irradiation of a metal‐free mixture of propargyl enol ethers and primary amines generates substituted alkyl 1,2‐dihydropyridine‐3‐carboxylates in excellent yields through a domino process (see scheme). The obtained 1,2‐dihydropyridines feature four possible diversity points and a chemical handle for complexity‐diversity generation (carboxylic ester at the C3 position).
一下子:微波照射炔丙基烯醇醚和伯胺的无金属混合物,可以通过多米诺工艺以极好的收率生成取代的1,2-二氢吡啶-3-羧酸烷基酯(请参见方案)。所获得的1,2-二氢吡啶具有四个可能的多样性点,并具有产生复杂性-多样性(C 3位置的羧酸酯)的化学手法。
