  • This introduces a new chiral center and NADPH is a cofactor.
  • This is due to the extra chiral center at C-2.
  • Styrene oxide has a chiral center and thus two enantiomers.
  • Multiple chiral centers are another bottleneck in the chemical synthesis of herboxidiene.
  • Mannose differs from glucose by inversion of the C-2 chiral center.
  • Are arranged around the chiral center carbon atom.
  • A mixture of enantiomers may contain two isomers of a molecule with one chiral center.
  • The chiral centers are indicated by asterisks.
  • 2-Methyltetrahydrofuran has one chiral center, so it exists in two enantiomeric forms.
  • A suprafacial transformation at a chiral center preserves stereochemistry, whereas an antarafacial transformation reverses stereochemistry.
  • Threonine is one of two proteinogenic amino acids with two chiral centers, the other being isoleucine.
  • There are eight chiral centers in the herboxidiene molecule and stereoselective methods are necessities of herboxidiene synthesis.
  • Given that the chiral center is adjacent to the carbonyl group, the molecule will racemize in solution.
  • The aldotetroses have two chiral centers ( " asymmetric carbon atoms " ) and so 4 different stereoisomers are possible.
  • This simple compound has a chiral center and is used sometimes to determine the enantiomeric resolution of simple chromatographic methods.
  • The chiral center need not be optically pure, as the relative stereochemistry will be the same for both enantiomers.
  • The D-" manno " prefix indicates that four chiral centers have the same configuration as D-mannose.
  • The substituent on the Cp is written in front of the F and the R on the chiral center after the F.
  • The ketotetroses have one chiral center and, therefore, two possible stereoisomers : erythrulose ( L-and D-form ).
  • The first total synthesis of isocomene was published by M . C . Pirrung in 1979 . The key steps are a chiral centers.
