- Method for preparing organic bromide by using micro-channel reactor
-
The invention discloses a method for preparing an organic bromide by using a micro-channel reactor. The method comprises the step of: performing a bromination reaction on a homogeneous solution formed by a compound shown in a formula I and a solvent and a homogeneous solution formed by a bromination agent and a solvent in the micro-channel reactor to obtain the organic bromide represented by a formula II, wherein the bromination reaction time is 1-10 minutes; the bromination reaction temperature is DEG C to 60 DEG C. The preparation method disclosed by the invention is extremely short, accurate to control reaction condition, high in safety and suitable for quick preparation of products, can be used for continuously production, and is low in cost. Moreover, by using the micro-channel reactor to prepare the organic bromide, the selectivity of reaction raw materials is high and the purity of a targerted compound is good, so that the preparation method is suitable for industrial production on a large scale.

- Novel syntheses of fluorenones via nitrile-directed palladium-catalyzed C-H and dual C-H bond activation
-
Novel procedures for the [Pd]/[Ag]/TFA system catalyzed cascade reactions of nitrile directed remote C-H and dual C-H bond activation with insertion of nitrile were developed, which afforded variously polysubstituted fluorenones in moderate to good yields with tolerance of a wide variety of substrates.

- Palladium-catalyzed desulfitative arylation by C-O bond cleavage of aryl triflates with sodium arylsulfinates
-
An efficient Pd-catalyzed desulfitative coupling reaction of sodium arylsulfinates as arylation reagents by C-O bond cleavage of aryl triflates was developed. With only 2 mol % of Pd(OAc)2 as catalyst and XPhos as ligand, the reaction proceeded well for a range of substrates.

- Nonpeptide angiotensin II receptor antagonists. I. Synthesis and biological activity of pyridine derivatives
-
Substituted pyridines were synthesized as potential angiotensin II (AII) receptor antagonists. Substitution at the position 2 in the pyridine resulted in potent activity, and the optimal alkyl length was four carbons. The potency further increased with the introduction of a hydroxymethyl group at the position 4. One of the compounds, 2-butyl-6-chloro-4-hydroxymethyl-5-methyl-3-[[2'-(1H-tetrazol-5-yl)bip henyl-4-yl]methyl]pyridine 9 h (KT3-579)is a competitive AII antagonist with a pA2 value of 9.31, and is about 10 times more potent than Du Pont 753. It was found to be an AT1 specific antagonist with an IC50 of 3.09 nM.
