Abstract The article describes ionic liquids [bmim][NO3] in the presence of 30% mol CuI as efficient media for the domino Knoevenagel–hetero–Diels–Alder reaction of o-propargyloxy benzaldehydes as unactivated terminal alkynes with some active methylene compounds. Short reaction time, easy workup, good to excellent yields, and mild conditions are advantages of this new media. Supplemental materials
摘要 本文描述了在 30% mol CuI 存在下离子液体 [bmim][NO3] 作为多米诺 Knoevenagel-hetero-Diels-Alder 反应的有效介质,邻炔氧基苯甲醛作为未活化的末端炔烃与一些活性亚甲基化合物。反应时间短、后处理容易、产率高到极好、条件温和是这种新培养基的优点。补充材料可用于本文。转至出版商的 Synthetic Communications® 在线版以查看免费的补充文件。图形概要
