Abstract

When both (2R)-[1-2H2]- and (2S)-[1-2H2]-glycerol are incubated with resting cell suspensions of S. cattleya, only the 2R-enantiomer labels the fluoromethyl groups of fluoroacetate and 4-fluorothreonine, with retention of both deuterium atoms, placing metabolic and mechanistic limitations on the process of biological fluorination.
