The regioselective 2,2,2-trifluoroethoxylation at the C5 position of amides derived from the 8-aminoquinoline has been developed. In the presence of PIDA, an unprecedented and undirected transition metal-free transformation was achieved using the readily available and appealing 2,2,2-trifluoroethanol as the fluorinated source. The selective distal 2,2,2-trifluoroethoxylation of an array of amides was achieved in moderate to good yields (12 examples, up to 61 % yield). This approach provided efficient access to high-value added fluorinated quinoline derivatives, key building blocks for bulk and fine chemical industry.

The objective of this study is to synthesize a series of sesamol-based phenolic acid derivatives, which were designed by combination principle. The hypolipidemic activity of all these compounds was preliminarily screened by acute hyperlipidemic mice model induced by Triton WR 1339, in which compound T6 exhibited more significant reducing plasma TG and TC than fenofibrate. Compound T6 was also found to obviously decrease TG and TC both in the plasma and hepatic tissue of high-fat-diet-induced hyperlipidemic mice. Moreover, T6 showed hepatoprotective effects, which remarkable amelioration in characteristic liver enzymes was examined and the histopathological observation displayed that compound T6 inhibited lipids accumulation in the hepatic. The levels of PPAR-α receptor related to lipids metabolism in hepatic tissue were upregulated after T6 treatment. Other potent effects of T6 such as antioxidant and anti-inflammatory activity were also observed. On the bases of these findings, compound T6 may serve as an effective hypolipidemic and hepatoprotective agent. [Figure not available: see fulltext.]
