Ruthenium Complex-Controlled Catalytic N-Mono- or N,N-Dialkylation of Heteroaromatic Amines with Alcohols.

The Journal of organic chemistry

Watanabe Y, Morisaki Y, Kondo T, Mitsudo Ta.
PMID: 11667318
J Org Chem. 1996 Jun 26;61(13):4214-4218. doi: 10.1021/jo9516289.

Heteroaromatic amines were N-alkylated with primary alcohols at 150-200 degrees C in the presence of a catalytic amount of various ruthenium complexes to give the corresponding monoalkylated and dialkylated amines in good to high yields. For example, 2-aminopyridine reacted...

Liver-specific genes and hepatocyte nuclear factor (HNF)-4alpha and -1 are coordinately regulated by extracellular matrix (ECM). However, still are unclear interactions between liver-specific genes and these liver-enriched transcription factors in the mechanism of hepatocyte differentiation regulated by ECM. To...

[reaction: see text] A one-pot synthesis and derivatization of diynes and triynes is reported. The polyyne framework is formed from a dibromoolefin precursor based on a carbenoid rearrangement, and the resulting Li-acetylide is then trapped in situ with an...

An efficient protocol for the stereoselective construction of multisubstituted fluorine-containing alkenes. A palladium-catalyzed bisstannylation of fluorinated internal alkynes.
