2-Methyltetrahydrofuran: A Green Solvent for Iron-Catalyzed Cross-Coupling Reactions

Iron-catalyzed cross-coupling reactions allow sustainable formation of C?C bonds using cost-effective, earth-abundant base-metal catalysis for complex syntheses of pharmaceuticals, natural products, and fine chemicals. The major challenge to maintain full sustainability of the process is the identification of green and renewable solvents that can be harnessed to replace the conventional solvents for this highly attractive reaction. Herein, iron-catalyzed cross-coupling of aryl chlorides and tosylates with challenging organometallic reagents possessing β-hydrogens is found to proceed in good to excellent yields with the green, sustainable, and eco-friendly 2-methyltetrahydrofuran (2-MeTHF) as solvent. The reaction operates with excellent functional group tolerance under very mild conditions. Furthermore, large-scale cross-coupling, cross-coupling of heteroaromatic substrates, and cross-coupling of challenging aryl tosylates and carbamates mediated by Fe–N-heterocyclic carbene catalytic systems in eco-friendly 2-MeTHF were also carried out. The developed method was applied to the key cross-coupling in the synthesis of a fibrinolysis inhibitor, further highlighting the potential of 2-MeTHF as a general solvent for sustainable iron-catalyzed cross-coupling reactions.

Structural Requirements and Docking Analysis of Amidine-Based Sphingosine Kinase 1 Inhibitors Containing Oxadiazoles

Sphingosine 1-phosphate (S1P) is a potent growth-signaling lipid that has been implicated in cancer progression, inflammation, sickle cell disease, and fibrosis. Two sphingosine kinases (SphK1 and 2) are the source of S1P; thus, inhibitors of the SphKs have potential as targeted cancer therapies and will help to clarify the roles of S1P and the SphKs in other hyperproliferative diseases. Recently, we reported a series of amidine-based inhibitors with high selectivity for SphK1 and potency in the nanomolar range. However, these inhibitors display a short half-life. With the goal of increasing metabolic stability and maintaining efficacy, we designed an analogous series of molecules containing oxadiazole moieties. Generation of a library of molecules resulted in the identification of the most selective inhibitor of SphK1 reported to date (705-fold selectivity over SphK2), and we found that potency and selectivity vary significantly depending on the particular oxadiazole isomer employed. The best inhibitors were subjected to in silico molecular dynamics docking analysis, which revealed key insights into the binding of amidine-based inhibitors by SphK1. Herein, the design, synthesis, biological evaluation, and docking analysis of these molecules are described.

LONG CHAIN BASE SPHINGOSINE KINASE INHIBITORS

The invention relates to inhibitors of sphingosine kinase enzymatic activity, compounds and pharmaceutical compositions that inhibit sphingosine kinase 1 and sphingosine kinase 2 (SphK1 and SphK2) enzymes and further relates to methods of treating diseases and disorders mediated by sphingosine 1 phosphate activity, comprising administering an effective amount of sphingosine kinase inhibitors.

A convenient synthesis of methyl 4-substituted benzoates via Diels-Alder reaction in the presence of palladium on activated carbon

The thermal reaction of methyl 2-oxo-2H-pyran-5-carboxylates with substituted styrenes in the presence of 10% palladium on activated carbon afforded directly the corresponding methyl 4-biphenylcarboxylates in good yields. By the similar procedure, methyl 4-heteroaryl- and 4-alkyl-substituted benzoates were obtained from heteroaromatic olefines and alkenes, respectively.

Reactions in Microemulsion Media. Nucleophilic Substitution Reactions of Benzyl and p-Alkylbenzyl Chlorides

A kinetic and synthetic study of nucleophilic displacement reaction of bromide ion with benzyl chloride (1a) and its p-ethyl-substituted (1b) and p-n-dodecyl-substituted (1c) analogues has been performed in microemulsions prepared from combinations of a 1.23:1 (w/w) mixture (S) of cetyltrimethylammonium bromide (CTABr) and 1-butanol, a 1:5 (w/w) KBr-H2O solution (W), and hexane (O).The rates of reaction decreased differentially with increasing hexane content at a constant ratio of S:W to indicate that the interphase was the microemulsion reactive site.For microemulsion with respect to aqueous micellar and aqueous ethanol reaction media, solubilization of substrate was higher, initial reaction rates were comparable or slightly less, and overall conversions were greater.
