Pd-Assisted Cross-Coupling Reactions with 4-Chlorocinnoline

[摘要]：A series of 4-ethynylcinnolines 3ae was prepared by Sonogashira reaction of 4-chlorocinnoline () with appropriate alkynes. Moreover, Suzuki coupling of with boronic esters gave the corresponding 4-arylcinnolines 5ac. Detailed NMR spectroscopic data including unambiguous chemical shift assignments of all 1H, 13C, and 15N resonances of the obtained cinnoline derivatives are reported.
