This Letter describes the use of alkene-terminated polyisobutylene (PIB) as a support for oxidizing agents. Two oxidizing agents, an ionically immobilized PIB-bound perruthenate oxidation catalyst and a PIB-bound 2-iodoxybenzoic acid (IBX) oxidizing reagent, were studied. A perruthenate catalyst ionically bound to PIB was prepared by binding the perruthenate anion to PIB that contained either a terminal tetraalkylammonium or an imidazolium salt. The PIB supported ammonium and imidazolium perruthenate were both selectively soluble in heptane and effective in the oxidation of alcohols. While these PIB-bound perruthenate catalysts could be readily separated from products, recycling was less successful. A PIB bound 2-iodoxybenzoic (IBX) oxidizing agent was coupled to a PIB support with an ester bond. It was highly soluble in nonpolar and moderately polar organic solvents. By taking advantage of PIB’s heptane solubility, the spent IBX reagent could be easily separated from products by a liquid/liquid heptane/acetonitrile biphasic separation. The recovered IBX reagent could then be regenerated and used in multiple cycles for oxidation of both primary and secondary alcohols.

Acridine derivatives constitute a class of compounds that are being intensively studied as potential anticancer drugs. Acridines are well-known for their high cytotoxic activity; however, their clinical application is limited or even excluded because of side effects. Numerous synthetic methods are focused on the preparation of target acridine skeletons or modifications of naturally occurring compounds, such as acridone alkaloids, that exhibit promising anticancer activities. They have been examined in vitro and in vivo to test their importance for cancer treatment and to establish the mechanism of action at both the molecular and cellular level, which is necessary for the optimization of their properties so that they are suitable in chemotherapy. In this article, we review natural and synthetic acridine/acridone analogs, their application as anticancer drugs and methods for their preparation. Copyright

Naturally occurring pyrrolizidine alkaloids (PAs) are isolated from plants and other sources. The interest of the scientific community in these compounds owes itself to their high toxicity and biological activity, as well as to the challenge of synthesizing their pyrrolizidine scaffold. This review encompasses a wide range of topics found in the literature from 1995 to date, including the occurrence, biosynthesis, toxicity (hepatotoxicity, genotoxicity, and tumorigenicity), biological activity, and pharmacological properties (glycosidase inhibitory activity) of these secondary metabolites. Particular attention is given to the chemistry of PAs, addressing general strategies for formal and total syntheses via amino-based substrates, pyrroles, and pyrrolidine-based derivatives.

In this review, we reported on the Proline-chimeras characterized by resembling the skeleton of Alanine (Alanine-Proline chimeras). The synthetic approaches were classified according to the position of the methyl group on the pyrrolidine ring. Moreover, the synthesis of pyroglutamic acid derivatives will be discussed due to its importance as building block and chiral pool in the asymmetric synthesis of numerous bioactive compounds. The present review will be focused on the chemical syntheses of mono-methyl substituted proline derivatives, including the contribution to the literature from 2004 to 2016.

Reference of 114615-82-6, An article , which mentions 114615-82-6, molecular formula is C12H28NO4Ru. The compound – Tetrapropylammonium perruthenate played an important role in people’s production and life.

A three-component coupling reaction of structurally simple 6?8 was successfully applied for expeditious synthesis of the 6/5/9-membered tricyclic structure 3 of cladieunicellin D (1) and klysimplexin U (2). Upon treatment with the Et3B/O2 reagent system, alpha-alkoxyacyl telluride 6, six-membered enone 7, and (Z)-4-hexenal (8) were linked in one pot to provide the densely functionalized 5 via sequential decarbonylative radical generation, radical addition, boron enolate formation, and intermolecular aldol reaction. Subsequent Lewis acid-promoted reductive etherification and SiO2-induced C10-epimerization gave rise to the cis-fused five-membered ether of 4. Finally, cyclization of the nine-membered ring was achieved by the ring-closing metathesis reaction, giving rise to 3. Compound 3 possesses the six stereocenters of 1 and 2, and would thus serve as an advanced intermediate for their total syntheses.

Oxidation of various alcohols is studied in the liquid phase under nitrogen atmosphere over vanadium phosphorus oxide catalyst in an environmental friendly protocol using hydrogen peroxide. The catalyst and the method are found to be suitable for the selective oxidation of a variety of secondary aliphatic, alicyclic and aromatic alcohols to the corresponding ketones. The catalyst is soluble in the reaction mixture; however, it could be re-used by the addition of new batch of substrate along with the solvent and oxidant to the previous reaction mixture. The reaction mechanism is expected to involve a redox cycle in which V 4+ in combination with dynamic V5+ sites are acting as the active centers. The active V4+ phase is expected to be a vanadium complex with oxo and phospho ligands.

Common oxidants used in chemical synthesis, including newly developed perruthenates, were evaluated in the context of understanding (and better appreciating) the sensitiveness and associated potential hazards of these reagents. Analysis using sealed cell differential scanning calorimetry (scDSC) facilitated Yoshida correlations, which were compared to impact sensitiveness and electrostatic discharge experiments (ESD), that enabled sensitiveness ranking. Methyltriphenylphoshonium perruthenate (MTP3, 8), isoamyltriphenylphosphonium perruthenate (ATP3, 7) and tetraphenylphosphonium perruthenate (TP3, 9) were found to be the most sensitive followed by 2-iodoxybenzoic acid (IBX, 2) and benzoyl peroxide (BPO, 10), whereas the most benign were observed to be Oxone (12), manganese dioxide (MnO2, 13), and N-bromosuccinimide (NBS, 17).

Tiglianes such as prostratin and related diterpenoids are biologically significant natural molecules and long-standing targets for organic synthesis community. Due to the complex polycyclic scaffolds, high oxygenation level, and dense functional groups and stereocenters, their de novo chemical syntheses still face formidable challenges despite extensive efforts in the past 40 years. This account details the development of a modular and concise synthesis of prostratin, a potent anti-HIV and anticancer agent. The key approach in this synthesis involved a sequence of oxidative dearomatization and sequential stereoselective installation of peripheral groups to rapidly build the contiguously substituted cyclohexane C-ring. Inspired by Wender’s work, an acid- A nd solvent-controlled stereodivergent formation of cyclopropane D-ring was developed. Mechanistic investigations by computational methods revealed that the competition between intra- A nd intermolecular hydrogen bonding led to different conformations, thus favoring different protonation processes. The designed and unexpected chemistry along this campaign reflected the uniqueness of the natural structures and should be amenable to future chemical syntheses of related complex polycyclic molecules.
