Relative Reactivity of anti- and syn-Oximino Carbonates and Carbamates of 2-Pyridylacetic Acid Esters
摘要:
[GRAPHICS]anti-Oximes of 2-pyridylacetic acid esters are rapidly transformed to pyridine-2-carbonitrile under a variety of conditions while syn-oximes bearing tert-butyl esters can be conveniently deprotected to the corresponding carboxylic acid with subsequent fragmentation to the nitrile.
