87392-05-0, Name is (R)-(+)-2-Tetrahydrofuroic acid, belongs to tetrahydrofurans compound, is a common compound. Formula: C5H8O3In an article, once mentioned the new application about 87392-05-0.

C(sp3)-H bond functionalization has emerged as a robust tool enabling rapid construction of molecular complexity from simple building blocks, and the development of asymmetric versions of this reaction creates a powerful methodology to access enantiopure sp3-rich materials. Herein, we report the stereoselective functionalization of C(sp3)-H bonds of cyclic ethers employing a photochemically active diaryliodonium salt in combination with an anionic phase-transfer catalyst. The synthetic strategy outlined herein allows for regio- and stereochemical control in the alpha-C-H acetalization of furans and pyrans using alcohol nucleophiles, thus providing the ability to control the configuration at the stereogenic exocyclic acetal carbon.

The flavour of thornless blackberries grown in Pacific Northwest including ‘Thornless Evergreen’, ‘Black Diamond’, ‘Black Pearl’, ‘Nightfall’, ORUS 1843-3, ‘Waldo’, NZ 9351-4, and ‘Chester Thornless’ as well as ‘Marion’ was profiled by sensory evaluation and instrumental analysis. Sensory results showed that ‘Marion’ and ‘Waldo’ had the lowest sweetness score, while NZ 9351-4 and ‘Thornless Evergreen’ had the highest sweetness scores. ‘Nightfall’ and ORUS 1843-3 had significantly lower sourness, while ‘Black Diamond’ and ‘Waldo’ had significantly higher sourness. The taste data only partly matched with the objective Brix and titratable acidity data. Descriptive aroma analysis indicated that ‘Black Diamond’, ‘Black Pearl’, ORUS 1843-3, and NZ 9351-4 were similar to ‘Marion’ in terms of fresh fruit, strawberry, floral, and raspberry aroma, while ‘Thornless Evergreen’, ‘Chester Thornless’, ‘Nightfall’, and ‘Waldo’ had more vegetal, woody, mouldy, and cooked fruit character. Instrumental analysis and calculated odour activity values (OAVs) indicated that furaneol, linalool, beta-ionone, 2-heptanol, and carvone could be the major aroma contributing compounds in these blackberries. Generalised Procrusters analysis (GPA) indicated the chemical analysis matched with descriptive sensory analysis. Odour-active compounds of furaneol, linalool, geraniol, ethyl hexanaote, trans-2-hexenol, and beta-ionone in ‘Marion’, ‘Black Diamond’, ‘Black Pearl’, ORUS 1843-3, and NZ 9351-4 could account for their similarity in fresh fruity, floral, strawberry, and raspberry aroma; while 1-octen-3-ol, myrtenol, eugenol, and alpha-terpineol in ‘Thornless Evergreen’, ‘Chester Thornless’, ‘Nightfall’, and ‘Waldo’ could account for their vegetal, woody, mouldy, and cooked fruit flavour.

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.
