Compounds having utility in medicine in countering cellular malfunction e.g. in conditions embraced by the general term “cancer”, which compounds normally exist us a keto-enol tautomeric pair, the racetalc keto form of which is rapresented by formula (Ia), wherein R is a hydrogen, lower alkyl, acyl, or another functional group of up to 6 carbons including at least one hetero atom, which atom may be directly bonded to the beta-carbon, which compound may be in the acylic form shown or in a cyclic form as equilibrium keto-enol tautomer derivatives and anomeric forms thereof, including enantiomers when R is hydrogen and diastereoisomers when R is another group. A method of obtaining such a compound comprises selecting an appropriate dihydrofuran having a protected primary alcohol side chain in the 2-position, subjecting the said protected alcohol side chain-substituted dihydrofuran to oxidation using a chromium-based reagent to yield the corresponding acid, subjecting said acid to iodolaetonisation conditions to yield the cis,cis,trans-trisubstituted iodo-lactone which upon displacement of the iodine provides the cis,cis,cis-tri-substituted hydroxylacetone which is capable of being reduced to obtain a lactol which is in equilibrium with the corresponding open chain aldehyde.

Prior to detailed process design, it is vital to first generate a good flowsheet that meets particular objective. This is particularly the case in bio-based materials and products, where, given a range of chemistries, the synthesis problem is not about the best way to make a particular product but rather the best way to convert a specific feedstock. In order to do so, an optimisation-based framework, which can be used to identify the optimal configuration of a process network that consists of both reactions and separation systems to achieve maximum economic potential, is presented in this paper. A process superstructure, which includes the concept of master reaction stages and subsidiary separation stages, is introduced to facilitate the theory. The problem is formulated as a generalised mixed integer linear programming (MILP) model which accounts for the simultaneous selection of products and identification of the process configuration. The solution of the optimisation problem includes the best possible economic performance, identification of active reactions, reaction ordering and separation sequences along with the corresponding flowsheet of the optimal process. The economic criterion takes account of raw materials costs, product values and separation related costs. Two bio-based chemical case studies are presented to illustrate the applicability of the proposed methodology.

4971-56-6, Name is Furan-2,4(3H,5H)-dione, belongs to tetrahydrofurans compound, is a common compound. name: Furan-2,4(3H,5H)-dioneIn an article, once mentioned the new application about 4971-56-6.

Two-spotted spider mite, Teranychus urticae (Acari: Tetranychide), is one of the most important agricultural pests throughout the world. The high reproductive potential, short life cycle, combined with frequent acaricide applications has resulted in resistance development to a wide range of acaricides. Resistance to acaricides has an important role in inefficiency of chemical control of this pest. In the present study, the susceptibility of two populations of two-spotted spider mite collected from Karaj (KrS) and Mahallat (MhR) to spirodiclofen was investigated. The bioassay was conducted using a leaf-dip method on same-age protonymphs. Bioassay results showed that there was a significant difference between LC50 values of KrS and MhR populations. The resistance ratio was obtained as 22.19. The synergistic effects of triphenyl phosphate (TPP), piperonyl butoxide (PBO) and diethyl maleate (DEM) were assessed using residual contact vial (RCV) bioassay method. Results of the synergistic studies showed significant differences between LC50 values of spirodiclofen with spirodiclofen + PBO and spirodiclofen + TPP in MhR population. The most synergistic effect in MhR population was related to PBO. The results of enzyme assays revealed that the most ratio activity in MhR population to KrS population was related to cytochrome P450 monoxygenase (3.02) and the lowest ratio activity was related to glutathione S-transferase (GST) (1.40). These results confirmed that esterase and cytochrome P450 monoxygenase are probably involved in resistance of T. urticae to s irodiclofen

Numerous biologically active natural products contain furanoses and pyranoses with mono- and dihydroxylated substituents. However, much of the structure-activity studies on such molecules is gathered on the aglycons without attention to the corresponding carbohydrate components. Consequently, there are few synthetic procedures that enable the rapid preparation of mono- and dihydroxyfuranoses and mono- and dihydroxypyranoses and no report for a 3,4-dihydroxyoxepanose. In this article we report the practical synthesis of orthogonally protected five-, six-, and seven-membered carbohydrate derivatives. The succinct manner in which these molecules were synthesized allows the rapid preparation of analogues aimed at discovering the role of ring size and individual hydroxyl moieties on the pyranose skeleton.
