The self-condensation of alkynals was for the first time implemented under mild organocatalytic conditions and was successfully linked with a domino organocatalytic inverse-electron-demand oxa-Diels–Alder reaction, which led to the development of a facile one-pot method to produce a wide variety of polysubstituted chiral 3,4-dihydropyrans with good to high yields and diastereoselectivities and high
炔烃的自缩合首次在温和的有机催化条件下进行,并成功地与多米诺骨牌有机催化逆电子需氧-Diels-Alder反应相关联,从而开发了一种简便的单锅法生产多种多取代的手性
3,4-二氢吡喃,具有良好至高收率,非对映选择性和高对映选择性。揭示了前所未有的炔基自缩合反应是通过仲胺催化的C-C三键
水合反应和随后的醛醇缩合反应进行的。
