English

Subject field(s)
  • Chemistry
DEF

The formation of a reaction product with a new chiral centre (and containing unequal amounts of the consequently generated stereoisomeric forms of the product) from a single precursor in which that centre was prochiral.

OBS

Such a step requires the use of an optically active material (reagent, solvent, catalyst, enzyme, etc.) or an optically active precursor (in which case the chiral forms that are produced in unequal amounts are diastereoisomers).

French

Domaine(s)
  • Chimie
DEF

Formation d'un produit de réaction constitué de quantités inégales de formes stéréoisomères et présentant un nouveau centre chiral, à partir d'un seul précurseur où ce centre était «prochiral» [...]

OBS

Pour une telle réaction, il est nécessaire de mettre en œuvre une substance optiquement active (réactif, solvant, catalyseur, enzyme, etc) ou un précurseur optiquement actif. Dans ce dernier cas, les formes chirales produites en quantités inégales sont des «diastéréoisomères». L'induction asymétrique, combinée à certains procédés de séparation, peut constituer une «synthèse asymétrique».
