New reactions of azomethine ylides with nontraditional dipolarophiles are reported. Azomethine ylides, formed in situ via decarboxylative condensations of alpha-amino acids with aldehydes, undergo reactions with naphthols, indoles, alkynes, and nitroalkanes.

A novel iron-catalyzed intermolecular decarboxylative Csp(3)-Csp(2) coupling reaction using proline derivatives as starting materials is developed. In this process, a series of potentially useful ligands (tertiary aminonaphthol) for catalysis was obtained.
Ruthenium-Catalyzed Hydrogen Evolution <i>o</i>-Aminoalkylation of Phenols with Cyclic Amines
hydrogen evolution ortho-aminoalkylation of phenolic derivatives with cyclic amines as the coupling agents. The developed cross-coupling reaction offers a practical platform for direct access to a variety of functionalized phenols with the features of good substrate and functional group compatibility, readily available catalyst system and feedstocks, no need for additional sacrificial oxidants, and high
