A practical, straightforward and one-step procedure for the synthesis of novel and stable β-amino-N-/O-hemiacetals (i.e. γ-aminoalcohols) is provided. The title compounds were obtained in good to excellent yields through an uncatalyzed three-component reaction by treatment of secondary amines with polyformaldehyde and electron-rich alkenes in acetonitrile as solvent at ambient temperature. The reactions proceeded with the formation of iminium ions, through a Mannich-type reaction, as the key intermediates for the generation of the target products. Single crystal X-ray analysis of derivative 4l confirmed unequivocally the structure and stability of the obtained compounds.

A novel and highly efficient heterogeneous catalytic reductive amination of aldehydes is described. The recently developed graphene supported NiPd alloy nanoparticle (G-NiPd) catalyst using ammonia borane (AB) as a green, stable and safe hydrogen donor was used in a water/methanol mixture (v/v = 2/3) under ambient conditions. The catalytic system was successfully applied in the reductive amination of various substituted aldehydes with amines and the corresponding products were obtained in (up to) 99% yield in 6 h. The G-NiPd catalyst could be recycled up to five times without any significant loss in the product yield.
Secondary amines: Synthesis and effect of length of spacer linking two phenyl rings on biological activity

experimental part, p. 1041 - 1044 (2009/12/24)
N-Benzyl benzylamines (1a-11a) and N-benzyl anilines (1b-11b) were synthesized by sodium borohydride reduction of aldimines of benzylamine and aniline respectively. The products were characterized on the basis of elemental analysis and spectral studies and screened for antifungal potential against four fungi and evaluated for nematicidal activity against two nematodes. The former compounds were found to be more effective as compared to the latter thus indicating an enhancement of biological activity due to introduction of an extra methylene group between two phenyl rings of aromatic secondary amines.
Use of polymer supported reagents for clean multi-step organic synthesis: Preparation of amines and amine derivatives from alcohols for use in compound library generation

The automated sequential application of polymer supported perruthenate (PSP) and polymer supported cyanoborohydride (PSCBH) in an oxidation-reductive amination procedure allowed the efficient transformation of simple alcohols into more complex amines which can be further derivatised by the use of polymer bound amino sulfonylpyridinium chlorides.
