Our laboratory has been interested in the development of synthetic tools and networks of reactions for efficient and selective chemical synthesis. In particular, we have been engaged in the chemistry of transition metal vinylidene complexes for catalytic alkyne functionaliztion. For the past several years, we have developed a range of reactions that are of broad potential utility in organic synthesis, which include carboxylative, alkylative, and hydrate cyclization reactions, and cycloisomerization reactions. In addition to these reactions, further explorations of a new mechanistic motif of metal-carbene oxidation have also led to the discovery of novel oxygenative alkyne addition reactions. The scope, mechanism and utility of the new processes will be discussed. Also presented in this talk will be our recent effort in the development of traceless C-C bond formations using organosulfur compounds. The new reaction forms C-C bonds stereoselectively by taking advantage of the reactivity of sulfone and allylic sulfinic acid functionalities, without leaving hints of the functional group unlike the traditional auxiliary chemistry. The details our studies will be described in this presentation.
