The present invention provides compounds useful for increasing cellular ATP binding cassette transporter ABCA1 production in mammals, and to methods of using such compounds in the treatment of coronary artery diseases, dyslipidiemias and metabolic syndrome. The invention also relates to methods for the preparation of such compounds, and to pharmaceutical compositions containing them.
The cationic ring-opening polymerization (CROP) of substituted 2-oxazolines using rare-earthmetaltriflates (RE(OTf)3) as initiator was investigated for the first time. In this work, we examined the polymerization characteristics of 2-ethyl-2-oxazoline (EtOx) initiated by Sc(OTf)3 under conventional thermal heating and microwave irradiation, and compared the respective outcomes with those obtained

with O, N, and S as the donor sites and are in the thiol form in all the complexes. Catalytic studies showed that all the complexes displayed good catalytic activity towards the reduction of nitriles and also the condensation of nitriles with 2-aminoalcohol under solvent-free conditions. Graphical Abstract
配体 9,10-菲醌-N4-取代的缩氨基硫脲 (HL1-3) 及其钌 (II) 配合物被合成并通过元素和光谱方法表征。配体是三齿一元螯合配体,以 O、N 和 S 作为供体位点,并且在所有配合物中都是硫醇形式。催化研究表明,所有配合物对腈的还原以及腈与 2-氨基醇在无溶剂条件下的缩合均表现出良好的催化活性。图形概要
