Abstract
A series of 4-pyridyl nonaflates was coupled with alkynes to efficiently provide new4-alkynyl-substituted pyridines. Apt conditions were developed for their conversion into furo[2,3-c]pyridines. 3-Pyridyl nonaflates offer access to regioisomeric furo[3,2-c]pyridines. An alternative cyclizationmethod employing iodine monochloride furnishes iodinated furo-pyridines which can undergo a second Pd-catalyzed step. Some of the newly prepared compounds are fluorescent and show strong Stokes shifts.
