The preparation of oxazolo[4,5-c]pyridine and 6-azaindole from 4-bromo-3-pivaloylaminopyridine (8) is reported. The oxazolopyridine 2-tert-butyl-oxazolo[4,5-c]pyridine (9) was successfully prepared from 8 in 78% yield by a new base/TBAB promoted non-

Palladium complexes of N-phenyl-2-pyridylamine (4) and dipyridylamine substrates (7, 11) have been studied. Due to the coordination ability of the pyridine-nitrogen atoms, the pyridyl substrates, 4, 7, 11 were subjected to Pd(OAc)2 complexations and

Based on new methodology for nitration of pyridine and pyridine derivatives developed at our department by Professor Jan Bakke and coworkers at NTNU, a whole range of substituted nitropyridines are now readily available. The method provides new possi
