The Heck reaction of Wang resin-bound allylamine with aryliodides produces various, substituted cinnamylamines. The catalyst and additive system consisting of palladium(II) acetate, n-Bu4NOAc and potassium chloride, in addition to potassium carbonate in N,N-dimethylformamide, accomplishes a regioselective γ-arylation. By utilising the easily formed and stable carbamate linker on Wang resin, the incompatibility
The first interruptedasymmetrichydroaminomethylation reaction was developed. The challenging trans-1,2-disubstituted olefins were employed as substrates, and a series of valuable chiral pyrrolidinones and pyrrolidines were obtained in high yields with high regioselectivities and excellent enantioselectivities. Several synthetic transformations were conducted, demonstrating the high synthetic utility
A range of ketone-stabilized phosphoniumylides were allylated with high regioselectivity by primary allylic amines in the presence of 5 mol % Pd(PPh3)4 and 10 mol % B(OH)3, and subsequent one-pot Wittig olefination gave structurally diverse α,β-unsaturated ketones in good to excellent overall yields with excellent E selectivity. The one-pot allylation/olefination reaction was extended to ester- and
