A variety of allylic acetates and derivatives were synthesized by an efficient two-step protocol that employs readily available terminal alkenes as starting materials. This method is highly regio- and stereoselective, affording the linear (E)- isomer as the sole adduct. This process tolerates several functional groups including halogen-containing molecules, and it is general for weak oxygen, carbon, nitrogen, and sulfur nucleophiles. Furthermore, adducts were obtained in good to excellent yields.

Metal-Free, Regio-and Stereoselective Synthesis of Linear (E)-Allylic Compounds Using C, N, O, and S Nucleophiles. -Bromination of alkenes (I) give the corresponding dibromides which are further converted into linear (E)-allylic compounds upon treatment with various nucleophiles. -(HUANG, X.; FULTON, B.; WHITE, K.; BUGARIN*, A.; Org.
