Reductive alkylation of amines with carbonyl compounds is a useful method for the production of N-alkylated amines, a rapid, mild, efficient, inexpensive and environmentally friendly procedure is reported for the reductive alkylation of amines with aromatic aldehydes using ammonium formate and NiCl2/...
reductive alkylationreductive aminationsecondary amines2‐11C]tert‐butanolThe development of a labeling method for secondary amines with [2- 11 C]acetone is described since the R 2 N -isopropyl moiety is present in many biologically active compounds. The influence of a variety of parameters (e.g...
A simple and convenient procedure for the reductive alkylation of primary and secondary amines and N,N-dimethylation of amino acids is described using sodium borohydride as a reducing agent in 2,2,2- trifluoroethanol without use of a catalyst or any other additive. The solvent can be readily ...

of chiral aliphatic amines has long been regarded as a paramount challenge. Mainstream approaches, including hydrogenation of enamines and imines, C–H amination, and alkylation of imines, were applied for the synthesis of chiral amines with circumscribed skeleton structures; typically, the chiral ...
The convenience and efficiency of using amidines as intermediates in the reductive monoalkylation of aromatic amines has been demonstrated. This monoalkylation can be performed as either a two-step synthesis or a one-pot procedure. Several examples are presented which clearly demonstrate the utility ...
