ChemInform Abstract: Palladium‐Catalyzed Chemoselective Allylic Substitution, Suzuki‐Miyaura Cross‐Coupling, and Allene Formation of Bifunctional 2‐B(pin)‐Substituted Allylic Acetate Derivatives.

Abstract

The allylic substitution of 2‐pinacolborane‐substituted allylic acetates (I) with nucleophiles (II) leads to boranes (III), which can be converted without isolation into ketones (IV) and trisubstituted alkenes (VI).
