Paragraph 0235-0240, (2021/07/28)
The invention belongs to the technical field of pyridineacetamide derivatives, and particularly relates to a pyridineacetamide derivative serving as a CDK inhibitor and a preparation method and application of the pyridine acetamide derivative. The pyridineacetamide derivative shows excellent CDK9/CDK7 enzyme inhibitory activity, and can be used for preparing drugs used for treating cancers, especially hematologic cancers including acute myeloid leukemia, multiple myeloma, chronic lymphocytic leukemia, follicular lymphoma and the like and solid tumors such as breast cancer, prostate cancer, ovarian cancer, hepatocellular carcinoma, pancreatic cancer, kidney cancer, stomach cancer, colorectal cancer, lung cancer and the like.
Preparation method of ibuprofen impurity A
-
Paragraph 0033-0035, (2018/12/02)
The invention discloses a preparation method of an ibuprofen impurity A (shown as a formula I). According to the preparation method, 3-methyl bromophenylacetate is used as a raw material and methyl onhydrogen is removed through alkali; then Suzuki reaction is carried out and the raw material is coupled with isobutaneboronic acid to generate 2-(3-isobutyl phenyl)methyl propionate; finally, the 2-(3-isobutyl phenyl)methyl propionate is hydrolyzed and neutralized to obtain the ibuprofen impurity A. The preparation method disclosed by the invention has the advantages that the raw material is cheap and easy to obtain, synthesis steps are simple, reaction conditions are moderate and the post-treatment is simple; a technology is stable and has good repeatability, so that the production cost isgreatly reduced, and commercial production and batch supply are facilitated.
Photochemical intramolecular amination for the synthesis of heterocycles

supporting information, p. 4798 - 4803 (2017/10/23)
Polycyclic heterocycles can be formed in good to excellent yields via photochemical conversion of the corresponding substituted aryl azides under irradiation with purple LEDs in a continuous flow reactor. The experimental set-up is tolerant to UV-sensitive functional groups while affording diverse carbazoles, as well as an indole and pyrrole framework, in short reaction times. The photochemical method is presumed to progress through a mechanism differing from the other methods of azide activation involving transition metal catalysis.

supporting information, p. 16072 - 16077 (2016/10/30)
The first stereoselective version of an iodine(III)-mediated rearrangement of arylketones in the presence of orthoesters is described. The reaction products, α-arylated esters, are very useful intermediates in the synthesis of bioactive compounds such as ibuprofen. With chiral lactic acid-based iodine(III) reagents product selectivities of up to 73 % ee have been achieved.
A Convenient Ruthenium-Catalysed α-Methylation of Carbonyl Compounds using Methanol

An efficient ruthenium catalyst is reported, for the first time, to catalyse the α-methylation of ketones and esters using methanol as a green methylating agent. The in situ generated catalyst from the complexes [RuCp*Cl2]2or [RuCp*Cl2]nwith dpePhos provided up to quantitative yields in the presence of only 20 mol% of lithium tert-butoxide (LiO-t-Bu) as a base. Regioselective mono- or multi-methylation could be effectively controlled by temperature. This catalyst system was also effective for the one-pot sequential α-alkylation–α-methylation of methyl ketones and conjugate reduction–α-methylation of α,β-unsaturated ketones to synthesise α-branched ketones. An application of the α-methylation of esters using the ruthenium catalyst was demonstrated for an alternative catalytic synthesis of Ketoprofen. (Figure presented.).

Non-steroidal anti-inflammatory drugs (NSAIDs) achieve their anti-inflammatory actions through an inhibitory effect on cyclooxygenase (COX). Two COX subtypes, COX-1 and COX-2, are responsible for the majority of COX activity at the gastrointestinal mucosa and in tissues with inflammation, respectively. We previously suggested that both gastric mucosal cell death due to the membrane permeabilization activity of NSAIDs and COX-inhibition at the gastric mucosa are involved in NSAID-induced gastric lesions. We have also reported that loxoprofen has the lowest membrane permeabilization activity among the NSAIDs we tested. In this study, we synthesized a series of loxoprofen derivatives and examined their membrane permeabilization activities and inhibitory effects on COX-1 and COX-2. Among these derivatives, 2-{4′-hydroxy-5-[(2-oxocyclopentyl)methyl]biphenyl-2-yl}propanoate 31 has a specificity for COX-2 over COX-1. Compared to loxoprofen, oral administration of 31 to rats produced fewer gastric lesions but showed an equivalent anti-inflammatory effect. These results suggest that 31 is likely to be a therapeutically beneficial and safer NSAID.
