As a means to make new benzofuran-embedded polycyclic structures, we established two efficient one-pot sequential coupling routes to 2-amino-3-arylbenzofurans and 2-amino-3-arylnaphtho[2,1-b]furans. Further ring formation (six- and seven-membered rings) with the resulting amine moiety at the C2 position of benzofurans was realized, leading to further expansion of benzofuran-based chemical space.

The diazatricyclic core of the madangamine alkaloids was synthesized from a densely functionalized cyclohexane derivative. An alkene and two cyanoformamide groups are used to form two new rings and a new quaternary stereocenter in a cascade reaction, which involves two Pd-catalyzed C-C bond activation steps. The synthesis of the cascade precursor involves an intramolecular Staudinger reaction of a vicinal diester that gives a [3.2.1]azabicyclooctane derivative, allowing the regioselective introduction of a monosubstituted alkene.

EGFR inhibitors are well-known as anticancer agents. Quite differently, we report our effort to develop EGFR inhibitors as anti-inflammatory agents. Pyrimidinamide EGFR inhibitors eliciting low micromolar IC50 and the structurally close non-EGFR inhibitor urea analog were synthesized. Comparing their nitric oxide (NO) production inhibitory activity in peritoneal macrophages and RAW 246.7 macrophages indicated that their anti-inflammatory activity in peritoneal macrophages might be a sequence of EGFR inhibition. Further evaluations proved that compound 4d significantly and dose-dependently inhibits LPS-induced iNOS expression and IL-1 beta, IL-6, and TNF-alpha production via NF-kappa B inactivation in peritoneal macrophages. Compound 4d might serve as a lead compound for development of a novel class of anti-inflammatory EGFR inhibitors.

An efficient and convenient pathway was developed for enantioselective synthesis of chiral sulfides by chiral bifunctional selenide-catalyzed electrophilic azidothio-lation and oxythiolation of N-allyl sulfonamides. By this protocol, a variety of chiral vicinal azidosulfides and oxysulfides were obtained in good yields with high enantioselectivities and diastereoselectivities. In this transformation, not only electrophilic arylthiolating reagents but also a wide range of electrophilic alkylthiolating reagents worked very well. The practical application of this method was elucidated by further transformations of the products into the diversified compounds.

Kiyokawa, K; Urashima, N; Minakata, S in [Kiyokawa, Kensuke; Urashima, Naruyo; Minakata, Satoshi] Osaka Univ, Grad Sch Engn, Dept Appl Chem, Osaka 5650871, Japan published Tris(pentafluorophenyl)borane-Catalyzed Formal Cyanoalkylation of Indoles with Cyanohydrins in 2021, Cited 64. The Name is 4-Methoxybenzaldehyde. Through research, I have a further understanding and discovery of 123-11-5.

Despite the significant achievements related to the C3 functionalization of indoles, cyanoalkylation reactions continue to remain rather limited. We herein report on the formal C3 cyanoalkylation of indoles with cyanohydrins in the presence of a tris(pentafluorophenyl)borane (B(C6F5)(3)) catalyst. It is noteworthy that cyanohydrins are used as a cyanoalkylating reagent in the present reaction, even though they are usually used as only a HCN source. Mechanistic investigations revealed the unique reactivity of the B(C6F5)(3) catalyst in promoting the decomposition of a cyanohydrin by a Lewis acidic activation through the coordination of the cyano group to the boron center. In addition, a catalytic three-component reaction using indoles, aldehydes as a carbon unit, and acetone cyanohydrin that avoids the discrete preparation of each aldehyde-derived cyanohydrin is also reported. The developed methods provide straightforward, highly efficient, and atom-economic access to various types of synthetically useful indole-3-acetonitrile derivatives containing alpha-tertiary or quaternary carbon centers.

An efficient synthesis of 1-arylideneamino-substituted hexahydro-1H-cyclopenta[d]pyrimidin-2-ones and octahydroquinazolin-2-ones has been developed. The synthesis involves a stereo- and regioselective cascade reaction of the corresponding 4-(tosylmethyl)semicarbazones with 1-morpholinocyclopentene or 1-morpholinocyclohexene to give predominantly bicyclic pyrimidines with an exocyclic C=C double bond (80-97%). The later undergo rapid isomerization when heated in THF in the presence of TsOH to form bicyclic pyrimidines with a significant predominance of those with an endocyclic C=C double bond (90-97%).

We report the synthesis of beta-lactams from alpha-ketoacylsilanes and imines, which proceeds via a formal [2+2] photochemical cycloaddition with in situ generation of siloxyketene. This mild and operationally simple reaction proceeds in an atom-economic fashion with broad substrate scope, including aldimines, ketimines, hydrazones, and fused nitrogen heterocycles, affording a variety of important beta-lactams with satisfactory diastereoselectivities in most cases. This reaction also features good functional-group tolerance, facile scalability and product diversification. Experimental and computational studies suggest that alpha-ketoacylsilanes can serve as photochemical precursors by engaging in a 1,3 silicon shift to the distal carbonyl group.

A simple, efficient and environment-friendly procedure for the synthesis of 5-arylidene rhodanines derivatives via a Knoevenagel type reaction was developed using rhodanine, a variety of differently substituted aldehydes and Na2SO3 as benign catalyst in ethanol. Selected 5-arylidene rhodanines were subjected to basic hydrolysis to afford 2-mercapto-3-substituted-acrylic acids. The presence of a boronic acid group is well tolerated in such transformations. In the case of 2-formylphenylboronic acid, this sequence opens access to a new benzoxaborole derivative. (C) 2020 Elsevier Ltd. All rights reserved.

Aim: Tumor cells adapt to hypoxic microenvironments by releasing the key transcription factor HIF-1 alpha, which promotes angiogenesis, glycolytic phenotype, metastasis and erythropoiesis, allowing proliferation amid low oxygen levels. Therefore, therapeutic targeting of HIF-1 alpha represents a viable strategy for cancer therapy. Methods & Results: The authors synthesized a series of novel tetrahydroquinazoline derivatives in six steps and demonstrated that their development had a unique ability to suppress HIF-1 alpha expression through proteasomal degradation. Conclusion: Among these compounds, CDMP-TQZ (8bf) exhibited the highest antiproliferative potency in human cancer cells, in part through downregulation of HIF-1 alpha.
