日期:2012.1.9
Novel aldehyde-functionalized ionic liquids have been synthesized and used as scavengers for primary amines in the synthesis of secondary amines. The yields of secondary amines are high (82-90%) with high purity. The advantages of the protocol over that with a polymer-supported aldehyde scavenger are the shorter reaction time, the homogeneous reaction medium, the high level of loading of the aldehyde group, easy monitoring of reaction, and characterization of intermediates.

the electronic characteristics of the 3-X substituent of the parent triazine molecule. However, L. major DHFR is more sensitive to the steric effects and polarizability of the 3-X substituent. Our results indicate that triazinesinhibit L. major promastigote growth via direct inhibition of DHFR as is shown by the good correlation between log 1/Ki values for inhibition of the purified enzyme and log

Synthesis of some novel 2-substituted benzothiazole derivatives containing benzylamine moiety as monoamine oxidase inhibitory agents
(4a-l) was designed and synthesized. The structures of the synthesized compounds were clarified using Fourier transform infrared spectroscopy (FTIR), proton nuclearmagneticresonance ((1)H-NMR), carbon-13 nuclearmagneticresonance ((13)C-NMR) and high-resolution mass spectrometry (HRMS) spectral data. Purity of synthesized compounds was checked by high-performance liquid chromatography (HPLC) analyses
