Asymmetrische Synthesen durch Substitution: Diastereomere Arsinite aus homochiral substituierten Arsoniten / Asymmetrie Synthesis via Substitution: Diastereomeric Arsinites from Homochirally Substituted Arsonites

  • Wolf Jürgen Richter

Conceptually novel access to chiral arsinites is provided by reacting phenyl-O,O-dimenthylarsonite (1) with bulky nucleophiles e. g. tert-butyl-lithium or iso-propyl-lithium to yield the arsinites 3 and 4. The asymmetric induction determined by GC and NMR is 50% and 30% d.e. A small nucleophile effects double substitution.
