A hydrogen-bond-catalyzed direct reductive amination of aldehydes is reported. The acid- and metal-free process uses thiourea as organocatalyst and the Hantzsch ester for transfer-hydrogenation and allows for the high-yielding synthesis of diverse amines.
An efficient and modular one-pot synthesis of polysubstituted aromatic amines by a mild reductive amination procedure is described and the biological potential of these nitrogen-centered compounds is demonstrated by growth inhibition of murine connective tissue cells and microscopy-based morphological studies.
