Copper(I)-catalyzed [3 + 2] cycloaddition of 3-azidoquinoline-2,4(1H,3H)-diones with terminal alkynesKafka, Stanislav (Avtor) Hauke, Sylvia (Avtor) Salčinović, Arjana (Avtor) Soidinsalo, Otto (Avtor) Urankar, Damijana (Avtor) Košmrlj, Janez (Avtor) cycloadditionazidesquinoline-24(1H3H)-dionesterminal alkynes123-triazoles3-Azidoquinoline-2,4(1H,3H)-diones 1, which are readily available from 4-hydroxyquinolin-2(1H)-ones 4 via 3-chloroquinoline-2,4(1H,3H)-diones 5, afford, in copper(I)-catalyzed [3 + 2] cycloaddition reaction with terminal acetylenes, 1,4-disubstituted 1,2,3-triazoles 3 in moderate to excellent yields. The structures of compounds 3 were confirmed by $^1$H and $^{13}$C-NMR spectroscopy, combustion analyses and mass spectrometry.20112021-09-06 09:38:20Članek v reviji129624sl
