Imidazo[4,5-b]pyridines are readily annelated (45-50 °C, 24-30 h, MeCN) with cyanoacetylenic tertiary -αalcohols to give stereoselectively functionalized 1,3-oxazolo[3,2-a]imidazo[4,5-b]pyridines in 50-88% yields. The adducts undergo a facile stereoselective hydrolytic dominorearrangement to functionalized derivatives of 2,3-diaminopyridines. ARKAT-USA, Inc.
