Total Synthesis and Structural Revision of Greensporone F and Dechlorogreensporone F

The first asymmetric total syntheses of the real isolation product (2S,5R,8R)-greensporone F and (2S,5R,8R)-dechlorogreensporone F, 14-membered resorcylic acid lactones with a cis-2,5-disubstituted tetrahydrofuran ring system, was accomplished. The synthesis features a late-stage Lewis acid-catalyzed stereoselective intramolecular oxa-Michael reaction, E-selective ring-closing metathesis, De Brabander’s esterification, and Jacobsen’s hydrolytic kinetic resolution as the key steps. Synthesis of both real isolation and erroneously proposed structure necessitated the revision of the absolute configuration of greensporone F and dechlorogreensporone F. The erroneous representation of (2S,5S,8S)-configuration in greensporone F and dechlorogreensporone F was assigned to be (2S,5R,8R) by comparison with the NMR data and specific rotation of the synthetic compounds with that of the reported data.Y

Facile In Situ 5-EMF Synthesis and Extraction Processes from Catalytic Conversion of Sugar under Sustainable Long-Life Cycle

The catalytic behavior for 5-ethoxymethylfurfural (5-EMF) formation was systematically studied via facile conversion of sucrose under a sustainable ultrasonic-biphasic system using an active ZnO nanofiber-deposited-SO3H-carbon catalyst (Zn-S-C). Interestingly, 5-EMF with a high yield could be easily obtained and separated from ethanol/tetrahydrofuran (THF) via green synthesis-extraction procedures in the presence of NaCl. Meanwhile, an actual 5-EMF yield of 93.5 +/- 0.8% was successfully achieved at 98 degrees C for 47 min using a THF amount (0.25 mol) and catalyst adding amount (77.8 wt %) over the combination of 2(k) factorial and Box-Behnken designs. The product selectivity and yield from sucrose conversion were systematically controlled by adjusting type/amount of catalyst, co-solvents or inorganic salts, and ultrasonic system. The activation energy (38.17 kJ/mol) obtained from ultrasound-assisted conversion of sucrose into 5-EMF was lower than that from the conventional system. Strikingly, a nonsignificant decrease in the turnover rate (TOR, min(-1)) for conversion of sucrose into 5-EMF appeared when the catalyst was reused up to 100 cycles, indicating long-life cycle stability of the as-prepared catalyst.

New learning discoveries about 585-88-6

As the paragraph descriping shows that 585-88-6 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.585-88-6,Maltitol,as a common compound, the synthetic route is as follows.

585-88-6, Comparative example – Continuous process without feed of NaOH; a) A tank was filled with Maltitol syrup at ca. 96% purity (C* Maltidex H 16330, Cerestar); the dry substance of the maltitol syrup was 45% b) The syrup was flowing through an heat exchanger (T=80C), followed by c) Flowing through the column with the anionic resin MSA-I , at a B VH=O.5 (Bed volume/hour).The treatment had to be stopped after 3.3 days (79 hrs), as the R.S-value remained the same as the R. S value of the maltitol feed.

Downstream synthetic route of 585-88-6

As the paragraph descriping shows that 585-88-6 is playing an increasingly important role.

585-88-6, Maltitol is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

585-88-6, It was tested whether the following saccharides could be used as substrates for alpha-isomaltosylglucosaccharide-forming enzyme. For the purpose, a solution of maltose, maltotriose, maltotetraose, maltopentaose, maltohexaose, maltoheptaose, isomaltose, isomaltotriose, panose, isopanose, alpha,alpha-trehalose, kojibiose, nigerose, neotrehalose, cellobiose, gentibiose, maltitol, maltotriitol, lactose, sucrose, erlose, selaginose, maltosyl glucoside, or isomaltosyl glucoside was prepared. To each of the above solutions was added two units/g substrate of a purified specimen of alpha-isomaltosylglucosaccharide-forming enzyme from either Bacillus globisporus C9 strain obtained by the method in Experiment 4-2, or Bacillus globisporus C11 strain obtained by the method in Experiment 7-2, and the resulting solutions were adjusted to give a substrate concentration of 2% (w/v) and incubated at 30 C. and pH 6.0 for 24 hours. The enzyme solutions before and after the enzymatic reactions were respectively analyzed on TLC disclosed in Experiment 1 to confirm whether the enzymes act on these substrates. The results are in Table 11. TABLE 11 Enzymatic action Enzymatic action Enzyme of Enzyme of Enzyme of Enzyme of Substrate C9 strain C11 strain Substrate C9 strain C11 strain Maltose + + Nigerose + + Maltotriose ++ ++ Neotrehalose + + Maltotetraose +++ +++ Cellobiose – – Maltopentaose +++ +++ Gentibiose – – Maltohexaose +++ +++ Maltitol – – Maltoheptaose +++ +++ Maltotriitol + + Isomaltose – – Lactose – – Isomaltotriose – – Sucrose – – Panose – – Erlose + + Isopanose ++ ++ Selaginose – – alpha,alpha-Trehalose – – Maltosylglucoside ++ ++ Kojibiose + + Isomaltosylglucoside – – Note: Before and after the enzymatic reaction, the symbols ?-?, ?+?, ?++?, and ?+++? mean that it showed no change, it showed a slight reduction of the color of substrate spot and the formation of other reaction product, it showed a high reduction of the color of substrate No.spot and the formation of other reaction product, and it showed a substantial disappearance of the color of substrate spot and the formation of other reaction product, respectively. As evident from Table 11, it was revealed that the alpha-isomaltosylglucosaccharide-forming enzyme well acted on saccharides having a glucose polymerization degree of at least three and having a maltose structure at their non-reducing ends, among the saccharides tested. It was also found that the enzyme slightly acted on saccharides, having a glucose polymerization degree of two, such as maltose, kojibiose, nigerose, neotrehalose, maltotriitol, and erlose.
