Abstract: Over the past 5 years, our group has developed a variety of calcium-catalyzed
transformations that lead to useful building blocks in a straightforward manner. In
particular, oxygen- and nitrogen-based heterocycles can be rapidly constructed by condensation reactions relying on C(sp3)-O bond activation, or cycloisomerization reactions triggered by C-C π-bond activation. These - and π-activations can be achieved in the presence of a catalytic amount of the calcium ion [Ca(NTf2)]+, which confers high levels of chemo-, regio-, and stereoselectivity. This presentation will summarize our findings in the development of novel synthetic methodologies based
on calcium catalysis.
