Pd-catalyzed C-2 arylation of oxazolo[4,5-b]pyridine proceeds efficiently at 30°C and tolerates a variety of aryl halides, including derivatized amino acids for which no racemization was observed during the reaction. Experimental evidence for facile depro

An efficient synthesis of a variety of pyridyl benzamides from 2-aminopyridines and nitroolefins is described. This rare-earth-metal-catalyzed reaction provides the corresponding products with broad substrate scope in moderate to excellent yields, in the absence of additives and external oxidants. Water is used as the source of the carbonyl oxygen atom in pyridyl benzamides. Furthermore, 2-substituted oxazolo[4,5-b]pyridines are formed in good yields under the standard conditions when 2-aminopyridin-3-ols are used as the substrates.

A new, simple, and efficient protocol is developed for the synthesis of 2-substituted benzoxazole derivatives through N-C-O bond formation using Al 3+-exchanged K10 clay (Al3+-K10) as catalyst. A wide range of benzoxazole derivatives
