Lignocellulosic biomass can be converted to significant platform molecule 5-hydroxymethylfurfural (HMF), from which one can envision a number of biofuels and chemicals through either chemical or biological conversions. Chemoselective hydrogenation is one of the important pathways for the upgrading of HMF into furanyl diols consisting of 2,5-bis(hydroxymethyl)furan (BHMF) and 2,5-bis(hydroxymethyl)tetrahydrofuran (BHMTHF). BHMF and BHMTHF are all-purpose intermediates for the manufacture of chemicals, fuels, and functional materials. In this context, we comprehensively summarized the studies on the chemoselective hydrogenation of HMF into furanyl diols in terms of different H-donors, including molecular H2, alcohols, formic acid, and other alternative H-donors. Through the systematic survey of the previous works, a feasible research direction is discussed for the production of furanyl diols.

Chemistry is traditionally divided into organic and inorganic chemistry. Application In Synthesis of (S)-(-)-alpha-Hydroxy-gamma-butyrolactone, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 52079-23-9

Commercially available N-Boc-4-O-benzyl-L-homoserine was treated with trifluoroacetic acid and the corresponding, N-deprotected derivative was submitted to deamination to give 4-O-benzyl-3-deoxy-L-glycero-tetronic acid (5). In another approach to 3-deoxy-L-glycero-tetronic acid protected at position 4, the carboxylic groups in L-malic acid were reduced, and the resulting triol was benzylidenated. Oxidation of the 2,4-O-benzylidene derivative formed with CrO3-pyridine complex in the presence of t-butyl alcohol gave t-butyl 2,4-O-benzylidene-3-deoxy-L-glycero-tetronate (13). The latter was saponified with aqueous sodium hydroxide to give, after Na+ exchange for H+, 2,4-O-benzylidene-3-deoxy-L-glycero-tetronic acid (15). Opening of the acetal ring in 13, followed by hydrolytic cleavage of the t-butyl ester function gave material indistinguishable from 5 obtained in the original way. When tested for their efficiency of N-acylation of derivatives of D-perosamine, both acids 5 and 15 gave the corresponding tetronamido derivatives in high yields.

A microwave-assisted regioselective synthesis of 3-functionalized indole derivatives via a three-component domino reaction of anilines, arylglyoxal monohydrates, and cyclic 1,3-dicarbonyl compounds is described. The main advantages of this protocol are short reaction times, practical simplicity, its metal-free nature, the availability of starting materials, green solvents, and high regioselectivity.

Microorganisms are found everywhere, and they are closely associated with plants. Because the establishment of any plant-microbe association involves chemical communication, understanding crosstalk processes is fundamental to defining the type of relationship. Although several metabolites from plants and microbes have been fully characterized, their roles in the chemical interplay between these partners are not well understood in most cases, and they require further investigation. In this review, we describe different plant-microbe associations from colonization to microbial establishment processes in plants along with future prospects, including agricultural benefits.

Synthetic Route of 89364-31-8, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.89364-31-8, Name is Tetrahydrofuran-3-carboxylic acid, molecular formula is C5H8O3. In a Article，once mentioned of 89364-31-8

A series of N2-[(acylamino)alkyl]-6,7-dimethoxy-2,4-quinazolinediamines was synthesized as potential alpha1-adrenoceptor antagonists. When administered to spontaneously hypertensive rats at 10 mg/kg po, a number of propanediamine derivatives showed good antihypertensive activity, whereas the ethanediamine derivatives, albeit being structurally more closely related to prazosin, were devoid of this property. The most active derivative, N-[3-[(4-amino-6,7-dimethoxy-2-quinazolinyl)methylamino]propyl]tetrahydro- 2-furancarboxamide hydrochloride, alfuzosin, showed high selectivity for peripheral alpha1-postjunctional adrenoceptors. At equiactive antihypertensive doses, its effect on the pressor response to postural changes in conscious dog was less marked than that shown by prazosin. In the light of these results, alfuzosin was selected for clinical evaluation.
