生物合成

In recent years, with the development of various good catalysts especially the ruthenium alkylidenes bearing N-heterocyclic carbene ligands, the RCM reaction has been applied widely in the synthesis of complex organic molecules, biological molecules and natural products etc. The Nobel Prize in Chemistry 2005 goes to Yves Chauvin, Robert H.
