Using N-acetyl-d-glucosamine as a starting material, the anti-influenza drugs oseltamivir and tamiphosphor were synthesized via a pivotal intermediate of aldehyde 8. An intramolecular Horner-Wadsworth-Emmons reaction was utilized to construct the highly functionalized cyclohexene ring. The existing N-acetyl group was transformed into an azido group for the subsequent aziridination, followed by implantation of a 3-pentoxy group of the desired stereochemistry.

Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. The appropriate choice can avoid electrode passivation, which strongly inhibit the efficient activation of substrates. 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11.

Twenty-one adducts of the form AgNO3:ER3:L (1:1:1) (E = P, As, Sb; R = Ph, cy, o-tolyl, mes; L = 2,2?-bipyridyl (‘bpy’)-based ligand), together with AgNO3:Pcy3:tpy (2:2:1) and AgNO3:PPh3:tpy (1:2:1) (‘tpy’ ? (2,2?:6,2?-terpyridine)), have been synthesized and characterized by analytical, spectroscopic (IR, far-IR, 1H and 31P NMR) and single crystal X-ray diffraction studies. The resulting complexes are predominantly of the form [(R3 E) AgL]+ NO3-, with trigonal EAgN2 coordination environments, the planarity of which is perturbed by the approach of the nitrate anion. The nitrate ion shows uni- or (semi-)bidentate coordination, excepting the complex AgNO3:P(o-tol)3:dpca (1:1:1) (dpca = bis(2-picolyl)amine) where the anion is uncoordinated, the donor dpca being a pincer-tridentate. The complex AgNO3:Pcy3:tpy (2:2:1), also reported, is dinuclear with a bridging unidentate nitrate and a terpyridine, the latter bridging through its central ring, with the peripheral rings forming chelates to either side, whereas the complex AgNO3:PPh3:tpy (1:2:1) is ionic with a five-coordinate silver, bonded to tridentate tpy and two phosphines.

In a Article，once mentioned of 2081-44-9, Formula: C5H10O2

A series of (8beta)-6-methyl-1-(1-methylethyl)ergoline-8-carboxylic acid cycloalkyl esters were prepared and examined for blockade of vascular 5HT2 receptors. The antagonist in this series that had the highest 5HT2 receptor affinity was (8beta)-6-methyl-1-(1-methylethyl)ergoline-8-carboxylic acid cyclohexyl ester (3). This compound was therefore chosen as the basic backbone of a structure-activity study to determine what effect different N1-substituents, N6-substituents, and ester ring substituents had on 5HT2 receptor affinity. Maximal 5HT2 receptor affinity was obtained when the N1-substituent was isopropyl, the N6-substituent was methyl, and there was a hydroxy or keto substituent in the 4-position of the ester cyclohexyl ring.

In a Article，once mentioned of 28244-94-2, Safety of 4-Methylphenyl 2,3,4,6-tetra-O-acetyl-1-thio-β-D-glucopyranoside

Structural, protecting group and leaving group effects in the formation of oxocarbenium intermediates were studied in the gas phase. It is found that significant stabilization of oxocarbenium cations is achieved by protecting groups that interact with the cationic center via neighboring group participation despite the electron-withdrawing character of these moieties. On the other hand, ethereal protecting groups do not facilitate the formation of oxocarbenium intermediates. The experimental findings are supported by DFT calculations that show the following order of stabilization by the group adjacent to the cationic center: RCO > SiR3 > R, where R is an alkyl group. This indicates that the SN1-like mechanism that is commonly proposed for this reaction is not always valid. Moderate leaving group effect is also detected in a series of thioaryl glucopyranosides.
