Enantioselective Synthesis of 5-epi-Citreoviral Using Ruthenium-Catalyzed Asymmetric Ring-Closing Metathesis [PDF]

, 2009
Chiral ruthenium olefin metathesis catalysts can perform asymmetric ring-closing reactions in ≥90% ee with low catalyst loadings. To illustrate the practicality of these reactions and the products they form, an enantioselective total synthesis of 5-epi ...

How and How Much Molecular Conformation Affects Electronic Circular Dichroism: The Case of 1,1-Diarylcarbinols

Molecules, 2018
Chiroptical spectra such as electronic circular dichroism (ECD) are said to be much more sensitive to conformation than their non-chiroptical counterparts, however, it is difficult to demonstrate such a common notion in a clear-cut way.

Pseudotetraivprolides from Pseudomonas entomophila Provide Insights into the Biosynthesis of Detoxin/Rimosamide‐Like Anti‐Antibiotics

Angewandte Chemie International Edition, EarlyView.
Pseudotetraivprolide is a new player among the Detoxin/Rimosamide‐like natural products! Its biosynthesis requires FabD from primary metabolism and a PipDFG complex for final‐step acetylation – unlocking its anti‐antibotic activity. Abstract Novel variants of known natural product (NP) classes can provide valuable insights into their biosynthesis ...

Ceramide structural features required to stimulate ABCA1-mediated cholesterol efflux to apolipoprotein A-I

Journal of Lipid Research, 2006
Ceramide is a component of the sphingomyelin cycle and a well-established lipid signaling molecule. We recently reported that ceramide specifically increased ABCA1-mediated cholesterol efflux to apolipoprotein A-I (apoA-I), a critical process that leads ...
