SYNTHESIS OF A NON-SYMMETRIC AZODICARBONYL COMPOUND AND ITS REGIOSELECTIVE REACTION WITH ORGANOMETALLIC REAGENTS

Article abstract of DOI:10.1016/0040-4039(91)80694-2

The non-symmetric azodicarbonyl compound 7 reacted with R-M/Lewis acid regioselectively at the nitrogen atom attached to the amide group giving 9, whereas it reacted with R-M at the nitrogen atom attached to the ester group producing 8 in high yield.
