Catalyst-controlled diastereoselectivity in the fluorination of chiral allylic amines enabled the preparation of highly enantioenriched 1,3-difluoro-2-amines bearing threecontiguousstereocenters. The enantioselective catalytic method was applied successfully to other classes of multifunctional alkene substrates to afford anti-β-fluoropyrrolidines, as well as a variety of 1,2-oxyfluorinated products
mL of toluene, Rh(acac)(CO)2 as the metal precursor, (S,R)-(N-Bn)Yanphos as the ligand, CO:H2 = 10:10 bar, S/C = 20, HSiEt3 (0.3 mmol), and BF3.Et2O (0.3 mmol) The configuration of all of the products was determined to be S, except for 4m; only the desired regioisomer was obtained as determined by NMR analysis.

Platinum-Catalyzed Direct Amination of Allylic Alcohols with Aqueous Ammonia: Selective Synthesis of Primary Allylamines
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.
