Transition metals catalyzed synthesis novel heterocyclic compounds
Based on my research experience and academic career, my research plan is to develop new synthetic reactions to create heterocyclic molecules having useful properties as functional materials or biological activities. Reactions I am going to study on can be classified into the following two categories. Project 1: Transition metal-catalyzed cascade cyclization and oxidative cross couplings reactio...
متن کاملMechanism of rhodium-catalyzed carbene formation from diazo compounds.
[reaction: see text] A large and normal nitrogen-15 kinetic isotope effect of 1.035 +/- 0.003 provides direct support for the proposed mechanism for the rhodium-catalyzed carbene formation from diazo compounds, which involves the fast formation of a metal-diazo complex followed by rate-limiting extrusion of N2. The large magnitude of the KIE indicates extensive C-N bond fission in the transitio...

متن کاملZinc-catalyzed synthesis of 2-alkenylfurans via cross-coupling of enynones and diazo compounds.
Inexpensive, less-toxic ZnCl2 serves as the catalyst for selective cross-coupling of enynones and diazo compounds, an unprecedented reaction pathway for zinc carbenoids. A cascade sequence comprising formal cyclization/cross-coupling leads to a variety of 2-alkenylfurans.
متن کاملAsymmetric synthesis of ethano-Tröger bases using CuTC-catalyzed diazo decomposition reactions.
Nonracemic ethano-bridged Tröger bases are prepared using CuTC-catalyzed decompositions of diazo compounds. Excellent levels of diastereo- and enantio-control (dr and ee up to 12:1 and 95% respectively) are now obtained with aryl diazoketone precursors.
