报道了一个在无金属参与的温和条件下,二氯甲烷(DCM)为溶剂,高氯酸三苯基碳正离子(Ph3CClO4)介导N-酰基二氢喹啉与类型多样的有机硼试剂的氧化C—H炔基化反应,高效合成了α-炔基取代的1,2-二氢喹啉化合物.此外,相应的C—H烯基化也可兼容,展示出了较好的合成利用价值.

An efficient synthesis of α-substituted 1, 2-dihydroquinoline compounds through the oxidative C—H functionalization of N-acyl-dihydroquinoline with diverse organoboron reagents mediated by triphenylcarbium perchlorate (Ph3CClO4) is reported. The reaction exhibits good functional group tolerance, allowing for C—H alkynylation and alkenylation proceeding smoothly in good yields.

Key words: dihydroquinoline, hydrocarbon functionalization, alkynylation, carbocation, oxidation
