ChemInform Abstract: Stereochemistry in the Reactions of (Z)‐ and (E)‐Allyltributylstannyl Reagents with Quinones.

Abstract

Lewis acid‐induced alkylation of the o‐quinones (I) and (VIII) or the p‐quinones (V) with the allylic tributylstannanes (II) or (XI) yields the α‐adducts (III), (VI), and (X) and/or the γ‐adducts (IV), (VII), and (IX).
