Enantioselective synthesis of alpha-hydroxy gamma-butyrolactones from an ephedrine-derived morpholine-dione

An ephedrine-derived morpholine dione is employed in the enantioselective synthesis of (S)-alpha-hydroxy gamma,gamma-dimethyl-gamma-butyrolactone and (S)-alpha-hydroxy gamma-butyrolactone. A one-pot alkylation/allylation protocol for the stereoselective conversion of the dione to 2-alkyl-2-allyl morpholinones, key intermediates for alpha-alkyl-alpha-hydroxy-gamma-butyrolactones, is described.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 52079-23-9 is helpful to your research. Related Products of 52079-23-9

Synthesis and comparative evaluation of 4-oxa- and 4-aza-podophyllotoxins as antiproliferative microtubule destabilizing agents

A series of novel 4-oxa-podophyllotoxin derivatives 7 featuring the intact lactone ring D and various substituents in rings B and E has been synthesized and evaluated in a phenotypic sea urchin embryo assay along with the representative 4-aza-analogs 5 for their antimitotic and microtubule destabilizing activity. The most active compounds exhibited myristicin-derived or a 3?,5?-dimethoxy substitution pattern in the ring E and a 6-methoxy moiety replacing the methylenedioxy ring A. Compounds 5xb, 5xe, 5yb, 7xa, 7xb, and 7xc showed potent antiproliferative effects in the NCI60 cytotoxicity screen. Notably, growth of the multi-drug resistant NCI/ADR-RES cells was more affected by these agents than the parent OVCAR-8 cell line. Although generally 4-oxa-podophyllotoxins were less potent than the respective 4-aza-derivatives in these assays, stability of the former series towards oxidation may prove to be of interest for the development of anticancer agents with in vivo activity.

The Preparation of Synthetic Analogues of Strigol

A range of analogues of the natural germination stimulant, strigol, for parasitic weeds of the genera Striga and Orobanche, has been prepared.Most of the products contain an alpha-formyl-gamma-lactone (or alpha-formyl-gamma-lactam) grouping attached through an enol-ether linkage to the 5-position of a but-2-enolide.Some have shown sufficiently high activities as to warrant large-scale field trials.

Electrochemical fluorination of several esters derived from oxolane-2-yl-carboxylic acid, oxolane-2-yl-methanol and oxane-2-yl-methanol

Electrochemical fluorination (ECF) of the ester derivatives of oxolane-2-yl-carboxylic acid (1), oxolane-2-yl-methanol (2) and oxane-2-yl-methanol (3) were investigated. Perfluoro(oxolane-2-yl- carbonylfluoride) (4) was obtained from derivatives of 1 and 2, and perfluoro(oxane-2-yl-carbonylfluoride) (5) was obtained from derivatives of 3 as the desired compounds, respectively. From the ECF of acetates of 2 and 3, perfluorospiroethers having a dioxolane ring were also obtained as the cyclization product in low yield together with the desired perfluoroacid fluoride (4 and 5). The structure of these perfluorospiroethers was confirmed by analyzing the chlorinated products, which were obtained by the reaction with AlCl3.

Phase Transition Enthalpy Measurements of Organic and Organometallic Compounds. Sublimation, Vaporization and Fusion Enthalpies From 1880 to 2015. Part 1. C1-C10

A compendium of phase change enthalpies published in 2010 is updated to include the period 1880-2015. Phase change enthalpies including fusion, vaporization, and sublimation enthalpies are included for organic, organometallic, and a few inorganic compounds. Part 1 of this compendium includes organic compounds from C1-C10. Part 2 of this compendium, to be published separately, will include organic and organometallic compounds from C11 to C192. Sufficient data are presently available to permit thermodynamic cycles to be constructed as an independent means of evaluating the reliability of the data. Temperature adjustments of phase change enthalpies from the temperature of measurement to the standard reference temperature, T = 298.15 K, and a protocol for doing so are briefly discussed.

Structural simplification of bioactive natural products with multicomponent synthesis: Dihydropyridopyrazole analogues of podophyllotoxin

A three-component condensation of 5-amino-3-methylpyrazole, tetronic acid, and various aromatic, heteroaromatic, and aliphatic aldehydes leads to the formation of dihydropyridopyrazole analogues of a cytotoxic lignan podophyllotoxin. This new heterocyclic scaffold-based library allows a drastic reduction of the structural complexity of the natural product with the retention of its potent cytotoxic properties. Similarly to podophyllotoxin, the presented analogues induce apoptosis in Jurkat cells.

Probes for the position and mechanistic role of the second ‘catalytic’ magnesium ion in the inositol monophosphatase reaction

Two magnesium ions are required for the enzymatic hydrolysis of phosphate monoesters substrates of inositol monophosphatase.It has been suggesested that one (buried) Mg2+ ion binds to the enzyme and the phosphate dianion moiety of the ubstrate through one or more of its negatively charged O-atoms while the second Mg2+ ion binds to the substrate bridging phosphate ester O-atom and one other substrate-derived O-atom.This second Mg2+ ion may also position and active the attacking nucleophilic water molecule. (A.G.Cole and D.Gani, J.Chem Soc., Perkin Trans 1, 1995, previous article).To determine the minimum structural requirements for a substrate, as deduced from the proposed interactions for natural and synthetic substrates with both Mg2+ ions,ethane-1,2-diol 1-phosphate was prepared and was found to be a substrate.The design and preparation of a range of minimal structure synthetic probes based on this new substrate including propyl, 2-methoxyethyl, 2-(2-hydroxyethoxy)ethyl and 5-hydroxypentyl monophosphate ester and both antipodes of 1,5-dihydroxypentan-2-yl phosphate allowed the specific interaction between the substrate and the enzyme and/or the second Mg2+ ion to be assessed.The results support the proposed roles for the metal ions and provide information on the position of the second Mg2+ ion.This information rationalises the properties of known organophosphate substrates and inhibitors for the enzyme and, furthermore, facilitates the construction of a 3-D catalytic mechanism for the inositol monophosphatase reaction which is described.This new catalytic mechanism explains why Li+ behaves as an inhibitor and accounts for its unusual inhibitory properties.
