ChemInform Abstract: Regio‐ and Stereoselectivity in the Reactions of Organometallic Reagents with an Electron‐Deficient and an Electron‐Rich Vinyloxirane: Applications for Sequential Bis‐allylic Substitution Reactions in the Generation of Vicinal Stereogenic Centers.

Abstract Under appropriate conditions, the reaction of vinyloxiranes (I) and (IX) with organometallic reagents can take place with high regio‐ and stereoselectivity.
