This review describes the synthesis of the frameworks of furo[2,3-b]-,
-[3,2-b]-, -[2,3-c]- and -[3,2-c]pyridine, and reactions of the furop
yridines: such as bromination, nitration, H-D exchange and lithiation
at the furan ring, chlorination, acetoxylation and cyanation of the N-
oxides of furopyridines an 2,3-dihydrofuropyridines, and conversion of
each substituent into other functional groups.
