Biocatalytic Synthesis of Stereospecific Triketide Lactones using Polyketide Synthases [PDF]
, 2016 Polyketide synthases are modular enzymes that create and modify large acyl chains. The domains and modules of polyketide synthases allow us to create molecules that resemble naturally occurring products by applying a biocatalytic in vitro in vivo ...

Ruthenium-Based Heterocyclic Carbene-Coordinated Olefin Metathesis Catalysts [PDF]
, 2010 The fascinating story of olefin (or alkene) metathesis (eq 1) began almost five decades ago, when Anderson and Merckling reported the first carbon-carbon double-bond rearrangement reaction in the titanium-catalyzed polymerization of norbornene.
