A catalytic β-selective addition of amines to styrenes proceeded in the presence of cationic Ru complexes combined with diphosphine ligands. In the reaction of α-methylstyrene, an enantioselective addition was achieved by using xylylBINAP.

Engineered biocatalysis: Here we show that the scope of reductive aminases (RedAms) can be extended to allow selective reductive aminations of cyclic secondaryamines, such as piperidines and morpholines, with both aldehydes and ketones. These biotransformations provide access to important motifs found in active pharmaceutical ingredients and other bioactive molecules.
