Trost, Barry M.;Jiao, Zhiwei;Liu, Ying;Min, Chang;Hung, Chao-I. Joey research published 《 Palladium-Catalyzed Enantioselective Cycloadditions of Aliphatic 1,4-Dipoles: Access to Chiral Cyclohexanes and Spiro [2.4] heptanes》, the research content is summarized as follows. Design and exploration of new intermediates for chemo-, regio-, and stereoselective cycloadditions remain a formidable challenge in modern organic synthesis. Compared to the well-developed 1,3-dipolar cycloadditions, Pd-catalyzed 1,4-dipolar cycloadditions are generally limited to specialized substrates due to the inherent nature of the thermodynamically driven intramol. transformations and undesired isomerizations. Herein, we demonstrate the use of ligated palladium catalysts to control and modulate the intermol. reactivity of aliphatic 1,4-dipoles, enabling two distinctive cycloaddition pathways with a broad scope of acceptors. This atom-economic process also features an eco-friendly in situ deprotonation strategy to generate the corresponding active palladium-mediated dipoles. Overall, a diverse array of chiral 6-membered rings and spiro [2.4] heptanes were prepared in high yield and selectivity. In addition, an unexpected property of cyano-stabilized carbanions was discovered and investigated, which can be useful in designing and predicting future transformations.

Treat, Anny;Henri, Vianie;Liu, Junke;Shen, Joyce;Gil-Silva, Mauricio;Morales, Alejandro;Rade, Avaneesh;Tidgewell, Kevin Joseph;Kolber, Benedict;Shen, Young research published 《 Novel TRPV1 Modulators with Reduced Pungency Induce Analgesic Effects in Mice》, the research content is summarized as follows. Capsaicin, the compound in hot chili peppers responsible for their pungency and an agonist of the transient receptor potential cation channel, subfamily V, member 1 (TRPV1), has long been known to promote the desensitization of nociceptors at high concentrations This has led to the utilization and implementation of topical capsaicin cream as an analgesic to treat acute and chronic pain. Critically, the application of capsaicin cream is limited due to capsaicin′s high pungency, which is experienced prior to analgesia. To combat this issue, novel capsaicin analogs were developed to provide analgesia with reduced pungency. Analogs reported in this paper add to and show some differences from previous structure-activity relationship (SAR) studies of capsaicin-like mols. against TRPV1, including the necessity of phenol in the aromatic “A-region”, the secondary amide in the “B-region”, and modifications in the hydrophobic “C-region”. This provided a new framework for de novo small-mol. design using capsaicin as the starting point. In this study, we describe the synthesis of capsaicin analogs, their in vitro activity in Ca²⁺ assays, and initial in vivo pungency and feasibility studies of capsaicin analogs YB-11 and YB-16 as analgesics. Our results demonstrate that male and female mice treated with YB capsaicin analogs showed diminished pain-associated behavior in the spontaneous formalin assay as well as reduced thermal sensitivity in the hotplate assay.

The mechanism of detection was studied using spectroscopic techniques revealed that the hydroxyl group is involved in the reaction with DCNP. The probes were found selective for the detection of DCNP in presence of other electrophilic interfering agents. Results were obtained in aqueous media and probes can be used directly for the rapid and sensitive detection of DCNP in water without any pretreatment.
