Abstract
A high-yield method for the introduction of a 2-pyridyl substituent in the C2 position of the three-membered ring of 2-bromo-2H-azirine-2-carboxylic acid derivatives by the direct cross-coupling with 2-(trialkylstannyl)pyridines has been described. The reaction works well with 3-, 4-, or 5-substituted 2-stannylpyridines and can be also employed for the synthesis of 2-(thiazol-2-yl)-2H-azirines. According to DFT calculations, the reaction proceeds through the sequence of SN2'-substitution of bromine, 1,4-stannyl shift, and [2,3]-sigmatropic shift of the pyridine ring.
