A new system for the selective synthesis of bisdimethylamine derivatives usingdiols and aqueous dimethylamine as the starting materials was developed. An iridium complex bearing an N-heterocyclic carbene ligand was used as the catalyst, and the reaction proceeded based on the borrowing hydrogen strategy in an aqueousmediumunder mild conditions. Various bisdimethylamine derivatives were obtained
Direct and selective synthesis of N,N-dimethylated amines from nitriles using methanol as C1 building blocks is reported using an air- and moisture-stable ruthenium complex. Following this process, various aromatic as well as aliphatic nitriles were converted to the corresponding N-methylated amines. Interestingly, tandem C-methylation as well as N-methylation was achieved by introducing multiple methyl

Aryltributyl- and aryltrimethyl-stannanes react with a range of N,N-dialkylmethylene-imonium salts to afford N,N-dialkylaminomethyl derivatives in good yields. The method can be used to obtain regloisomers that are not available using classical procedures. “In situ” reactions can also be carried out using alkoxydialkylaminomethanes (aminol ethers) and bis(dialkylamino)methanes (aminals) together with

The synthesis of symmetric dimeric camphor derivatives containing two quaternary nitrogen atoms was performed and their myorelaxant activity in mice was evaluated. For the comparison, some saltsderivedfrom meta- and para-xylylene dibromides were synthesized and their activity was tested.
