A series of five 2-(2-hydroxyphenyl)oxazolo [4,5-b]pyridines (HPOP) (3a-e), where four are novel, were synthesized by a mild, one pot, phenylboronic acid-NaCN catalyzed reaction. Spectroscopic characterization and photophysical properties of these co

A novel, one-pot, phenylboronic acid catalyzed, cyanide promoted synthesis of 2-(2-hydroxyphenyl)benzoxazoles from salicylaldehydes and o-aminophenols is described. The synthesis is characterized by mild conditions, short reaction times, and simple w

The 2-arylbenzoxazoles 3a – f were produced in moderate to excellent yields merely by stirring a potassium cyanide (3 equiv)-containing methanol solution of the borobicyclic compounds 1a – f at room temperature. These compounds were fully charact

The generality of the mild and efficient procedure is shown by synthesis of 19 derivatives of type (II) and (V) and extension to the preparation of methylene bis-benzoxazoles (VIII).

Treatment of the boron substrates (I) with KCN does not cause addition of cyanide to the double bond, as expected, but leads to formation of 2-arylbenzoxazole products.
