英文摘要
Project Summary/Abstract
Transition metal catalyzed cross coupling is one of the most important strategies in
complex molecule synthesis. This approach has been widely applied in medicinal and
biological research for drug candidate preparation and for biological target
modification/functionalization. Despite the great successes during the last two decades,
there are remaining challenges that need to be addressed. The three problems in
coupling type transformations that we would like to address in this proposal are A)
controlling selectivity on cross coupling while alkynes are involved, B) increasing the
efficiency of forming large macrocycles through catalytic coupling process, and C)
extending the choice of coupling partners, such as amine and F-, as compatible
functional groups for coupling type transformations. The general scheme of the
proposed research is the ligand-assisted gold redox catalysis, recently developed from
PI’s lab. Compared with the conventional coupling methods, gold chemistry offers
some unique reactivity, including fast reductive elimination, selective formation of gold
acetylide and ligand-assisted diazonium activation through nitrogen extrusion. These
properties provide new opportunities to address some of the long-existing challenges in
metal catalyzed cross coupling. The proposed research is innovative because it
focuses on the impact of new reactivity offered by this recently developed Au(I)/Au(III)
redox catalysis toward challenging C-C and C-X coupling transformations. These
investigations are also significant and will advance pharmaceutical and medicinal
research by providing new strategies to achieve complex molecule synthesis.
