On the stereochemistry of ethylene biosynthesis
Abstract
The convertion of (i) an equal mixture of the two isomers of cis-2,3-dideuterio-1-aminocyclopropanecarboxylate or (ii)(±)-trans-2,3-dideuterio-1-aminocyclopropanecarboxylate by apple slices gave in both cases a 1:1 mixture of cis- and trans-1,2-dideuterioethylene; in contrast the chemical oxidation (NaOCl) of these substances proceeded with complete retention of configuration to cis-dideuterioethylene and trans-dideuterioethylene, respectively.
