A straightforward synthesis of enantiopure (S)- and (R)-[alpha]-Tfm-pyroglutamic acid is reported. The strategy is based on the use of a chiral CF3-hydroxy... Gregory Chaume,Marie-Celine Van Severen,Louis Ricard - 《Journal of Fluorine Chemistry》 被引量: 0发表: 2008年 A straightforward...
(complex I) inhibitors in the mitochondrial electron transport chain. Because of the significant activities of the piericidins, which include insecticidal, antimicrobial and antitumor effects, total syntheses of the piericidins were developed using various synthetic strategies. The biosynthetic origin of ...

More Tricks in the R and S configurations What if you are comparing two carbons;one connected to three high-atomic number elements, and the other one with two hydrogens and a heteroatom. Which one gets a higher priority? Let’s see this with this molecule: ...
Laterally lithiated (S)-(−)- and (R)-(+)-o-toluamides 6 with a chiral auxiliary derived from (S)- and (R)-phenylalaninol, respectively, were used as the building blocks and chirality inductors in the asymmetric modification of the Pomeranz–Fritsch–Bobbitt synthesis of isoquinoline alka...
The hydrogen isotopes deuterium (D) and tritium (T) have become essential tools in chemistry, biology and medicine1. Beyond their widespread use in spectroscopy, mass spectrometry and mechanistic and pharmacokinetic studies, there has been considerable interest in incorporating deuterium into drug molecul...
