An efficient synthesis of bicyclic heterocycles has been realized from L-glutamic acid. The key step is the construction of the pyrrole ring in a single step, using tosylmethyl isocyanide (TosMIC) methodology. Structures of reaction intermediates and final products were investigated using density functional theory calculations.

Total syntheses of the microtubule stabilizing antitumor drugs epothilone B and D are described, starting from optically pure (S)-malic acid and methyl (R)-3-hydroxy-2-methylpropionate. The synthesis is highly convergent by coupling the three fragments C1-C6 (fragment D), C7-C10 (fragment C), and C11-C21 (fragment B). Key steps are two stereoselective Wittig type olefinations to generate the 12,13- and 16,17-double bonds, an enantioselective Mukaiyama aldol addition to synthesize fragment D, and a sulfone anion allyl iodide alkylation to connect fragments B and C. Finally fragment D was attached to the B + C fragment via aldol addition.

Related Products of 21461-84-7, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 21461-84-7, molcular formula is C5H6O4, introducing its new discovery.

Human immunodeficiency virus type 1 (HIV-1) protease inhibitors containing four types of hydroxyethylene dipeptide isosteres were designed and synthesized. These inhibitors consist of eight stereoisomers of phenylalanylproline (Phe-Psi[H.E.]-Pro), four stereoisomers of phenylalanylalanine (Phe-Psi[H.E.]-Ala), and one stereoisomer each of phenylalanylglycine (Phe-Psi[H.E.]-Gly) and cyclohexylalanylalanine (Cha- Psi[H.E.]-Ala) hydroxyethylene dipeptide isosteres. For the synthesis of the latter two isosteres, a newly developed synthetic method for y-lactone was applied. The inhibitory activities of these peptides were evaluated by cleavage assay of partially purified gag proteins or purified synthetic peptide. Of the inhibitors examined, compounds 2c (Z-Asn-(2S,3R,4S,5S)-Phe- Psi[H.E.]-Pro-NHBu(n); Bu(M) = n-butyl, K(i) = 0.50 muM), 21a (Z-Asn- (2R,4S,5S)-Phe-Psi[H.E.]-Ala-NHBu(n), K(i) = 0.34 muM) and 23 (Z-Asn- (2R,4S,5S)-Cha-Psi[H.E.]-Ala-NHBu(n), K(i) = 0.46 muM) were moderately potent inhibitors. The results revealed that the alkyl substituent at C2 is essential, and the stereochemistry of the hydroxyethylene dipeptide isosteres greatly affected their inhibitory activities.

Samarium(II) di-iodide, which is a strong one-electron transfer reducing agent, is effective for the reductive coupling of alpha,beta-unsaturated esters with carbonyl compounds, whereby substituted gamma-lactones can easily be prepared in good to excellent yields under very mild conditions.Two mole equiv. of samarium(II) di-iodide to each mole equiv. of starting substrate always give reasonable yields.The presence of an alcohol is essential in the reaction, complex unidentified products being formed in the absence of an alcohol; t-butyl alcohol gave more satisfactory results than methanol and ethanol.The alcohol acts as a proton donor, the use of MeOD leading to a deuteriated gamma-lactone.The reaction is applicable to both aliphatic and aromatic ketones or aldehydes, whereas the electrochemical method is limited to aliphatic substrates.The diastereoselectivity is examined in the reaction of 4-t-butylcyclo-hexanone with ethyl acrylate; an anti-isomer is produced predominantly (syn:anti = 1:9) as the result of selective axial attack.The reaction may proceed by a radical mechanism, and reaction may not involve a samarium ester homoenolate.The reaction is extended to the intramolecular reaction of an alpha,beta-unsaturated keto ester (8-oxonon-2-enoate) leading to the ready synthesis of a bicyclic gamma-lactone.

15833-61-1, Name is (Tetrahydrofuran-3-yl)methanol, belongs to tetrahydrofurans compound, is a common compound. Formula: C5H10O2In an article, once mentioned the new application about 15833-61-1.

A new series of arachidonic acid derivatives were synthesized and evaluated as inhibitors of the endocannabinoid uptake. Most of them are able to inhibit anandamide uptake with IC50 values in the low micromolar range (IC50 = 0.8-24 muM). ln general, the compounds had only weak effects upon CB1, CB2, and VR1 receptors (Ki > 1000-10000 nM). In addition, there was no obvious relationship between the abilities of the compounds to affect anandamide uptake and to inhibit anandamide metabolism by fatty acid amidohydrolase (FAAH; IC50 = 30-113 muM). This indicates that the compounds do not exert their effects secondarily to FAAH inhibition. It is hoped that these compounds, particularly the most potent in this series (compound 5, UCM707, with IC50 values for anandamide uptake and FAAH of 0.8 and 30 muM, respectively), will provide useful tools for the elucidation of the role of the anandamide transporter system in vivo.

Euphorbia factor L3, a lathyrane diterpenoid extracted from Euphorbia lathyris, was found to display good anti-inflammatory activity with very low cytotoxicity. To find more potent anti-inflammatory drugs, two series of Euphorbia factor L3 derivatives with fatty and aromatic acids were designed and synthesized. Among them, lathyrane derivative 5n exhibited most potent inhibition on LPS-induced NO production in RAW264.7 cells with no obvious cytotoxicity. To determine the key characteristics of Euphorbia factor L3 derivatives that contribute to anti-inflammatory activity, we conducted a structure-activity relationship study of these compounds.
