Iodoalkene-Based Approach Towards Carboxamides of Biological Importance: Aminocarbonylation of 2-Iodobornene and 3-Iodo-2- quinuclidene

The palladium-catalysed aminocarbonylation of 2-iodobornene and 3-iodo-2-quinuclidene, possessing iodo alkene functionality, resulted in the high-yielding synthesis of the corresponding carboxamide derivatives. The substrates were synthesised from camphor and 3-quinuclidone, respectively, via their hydrazones. The chemoselective homogeneous carbonylation reaction of synthetic value was carried out under mild reaction conditions. While the carbonylation of the 2- iodobornene was found to be a facile reaction with yields of synthetic interest, its isomer, 1-iodocamphene, formed in Wagner-Meervein rearrangement, remained intact under the same reaction conditions.
