Outline of Final Research Achievements |
We have studied on new synthetic methods of coelenterazine analogues with the aim of development of a near-infrared bioluminescence system. As the results, we found that four substituents could be introduced into easily accessible 2-amino-3,5-dibromo-6-chloropyrazine via successive palladium-catalyzed cross-coupling reactions. Moreover, a phenyl group equipped with a free hydroxy group at the ortho position was also applicable for the cross-coupling reaction. The hydroxy group could be transformed into a triflyloxy group, which was found to be useful for construction of a cyclic system containing the pyrazine ring.
