Direct amination of unactivated allylic alcohols with aqueousammonia was catalyzed by a Pt/phosphine complex to give the corresponding allylamines along with water as the sole by‐product. Under optimized reaction conditions, primary allylamines were obtained as major products with excellent monoallylation selectivity. cod=1,5‐cyclooctadiene.
A general and convenient palladium‐catalyzed oxidative Heck arylation of both N‐protected and N,N‐diprotected allylic amines with arylboronic acids under mild conditions has been developed. The catalyst system, consisting of Pd(OAc)2 (palladium acetate), AgOAc (silver acetate) and KHF2 (potassium hydrogen fluoride), could efficiently catalyze the coupling reaction in acetone without the aid of any
Following an extensive screening of reaction parameters such as the nature and amount of bases, Pd pre‐catalysts, ligands, additives, solvents and temperature range, we succeeded in developing a Heckreaction using N‐Boc‐allylamine and commercially available aryl bromides, capable of delivering a wide range of Boc‐protected trans‐cinnamylamines with 75–85 % regio‐ and stereoselectivity over other isomers
