Petti, Alessia,Natho, Philipp,Lam, Kevin,Parsons, Philip J.
, p. 854 - 858 (2021/01/12)
A mild electrochemical method for the regioselective preparation of 1-tetralones under environmentally friendly conditions from readily available cyclobutanols was developed. A series of aromatic- and heteroaromatic-fused 1-tetralones was accessed through ring expansion of the functionalized cyclobutanols via electrochemical generation of alkoxy radicals and intramolecular cyclization.

An intramolecular arene alkylation reaction has been developed using the organic photocatalyst 4CzIPN, visible light, and N-(acyloxy)phthalimides as radical precursors. Reaction conditions were optimized via high-throughput experimentation, and electron-rich and electron-deficient arenes and heteroarenes are viable reaction substrates. This reaction enables access to a diverse set of fused, partially saturated cores which are of high interest in synthetic and medicinal chemistry.
Synthesis of Benzannulated Medium-ring Lactams via a Tandem Oxidative Dearomatization-Ring Expansion Reaction
Guney, Tezcan,Wenderski, Todd A.,Boudreau, Matthew W.,Tan, Derek S.
, p. 13150 - 13157 (2018/09/10)
Medium-ring natural products exhibit diverse biological activities but such scaffolds are underrepresented in probe and drug discovery efforts due to the limitations of classical macrocyclization reactions. We report herein a tandem oxidative dearomatization-ring-expanding rearomatization (ODRE) reaction that generates benzannulated medium-ring lactams directly from simple bicyclic substrates. The reaction accommodates diverse aryl substrates (haloarenes, aryl ethers, aryl amides, heterocycles) and strategic incorporation of a bridgehead alcohol generates a versatile ketone moiety in the products amenable to downstream modifications. Cheminformatic analysis indicates that these medium rings access regions of chemical space that overlap with related natural products and are distinct from synthetic drugs, setting the stage for their use in discovery screening against novel biological targets.

Ao, Jun,Liu, Yidong,Jia, Shiqi,Xue, Lu,Li, Dongmei,Tan, Yu,Qin, Wenling,Yan, Hailong
supporting information, p. 433 - 440 (2018/01/03)
An unprecedented PTSA-promoted furan annulation and aromatization in one pot has been developed. This process offers a simple and efficient synthetic route for the construction of various highly substituted benzo[b]furan derivatives, which are widely used not only in drug active molecules but also organic semiconductor and organic light-emitting devices. The preliminary mechanism study indicated this transformation proceeded sequentially via furan annulation and aromatization.
Method for synthesizing tetralone compound
-
Paragraph 0029; 0030, (2016/10/07)
The invention belongs to the technical field of organic compound synthesis, provides a method for synthesizing a tetralone compound, and aims at solving the problems that in an exiting tetralone compound synthesizing method, an expensive transition metal catalyst, such as a palladium catalyst, is needed, and a large quantity of oxidizing agent is needed during a reaction. Aryl is used for replacing cyclobutanol to serve as an initiator, under the action of a catalyst, an oxidizing agent and an additive, reacting is carried out for 1-8 h in a solvent at the temperature of 25 DEG C to 100 DEG C, and the tetralone compound is obtained. The method has the advantages that the reaction conditions are relatively moderate, cheap metal copper is adopted as the catalyst, ligand participation is not needed, and operation is easy, convenient and feasible.
Discovery of Potent and Selective Agonists of δ Opioid Receptor by Revisiting the "message-Address" Concept
Shen, Qing,Qian, Yuanyuan,Huang, Xiaoqin,Xu, Xuejun,Li, Wei,Liu, Jinggen,Fu, Wei
supporting information, p. 391 - 396 (2016/05/19)
The classic "message-address" concept was proposed to address the binding of endogenous peptides to the opioid receptors and was later successfully applied in the discovery of the first nonpeptide δ opioid receptor (DOR) antagonist naltrindole. By revisiting this concept, and based on the structure of tramadol, we designed a series of novel compounds that act as highly potent and selective agonists of DOR among which (-)-6j showed the highest affinity (Ki = 2.7 nM), best agonistic activity (EC50 = 2.6 nM), and DOR selectivity (more than 1000-fold over the other two subtype opioid receptors). Molecular docking studies suggest that the "message" part of (-)-6j interacts with residue Asp1283.32 and a neighboring water molecule, and the "address" part of (-)-6j packs with hydrophobic residues Leu3007.35, Val2816.55, and Trp2846.58, rendering DOR selectivity. The discovery of novel compound (-)-6j, and the obtained insights into DOR-agonist binding will help us design more potent and selective DOR agonists.

A regioselective synthesis of 1-tetralones via silver-catalyzed ring expansion is described. A variety of 1-tetralones are furnished under mild reaction conditions from tertiary cyclobutanols regardless of the electronic properties and steric hindrance of substituents, providing a new and practical method to access diverse 1-tetralone building blocks. Preliminary experimental and DFT studies revealed that a radical-mediated sequence of C-C bond cleavage/C-C bond formation is involved.
