Cooperative Catalysis: Calcium and Camphorsulfonic Acid Catalyzed Cycloisomerization of Diynols.

Chemistry (Weinheim an der Bergstrasse, Germany)

Rauser M, Schroeder S, Niggemann M.
PMID: 26403228
Chemistry. 2015 Nov 02;21(45):15929-33. doi: 10.1002/chem.201503293. Epub 2015 Sep 25.

The first transition metal-free cycloisomerization of easily accessible diynols is presented as a novel approach to bicyclic 2H-pyrans. As a one-step protocol, the reaction proceeds in a single reaction cascade by intertwining mechanistic fragments borrowed from transition metal-catalyzed Claisen...

Curr Ther Res Clin Exp. 2003 Nov;64(9):685-96. doi: 10.1016/j.curtheres.2003.09.014.

BACKGROUND: The role of platelets in acute cardiovascular atherothrombotic events has been well established and attention has focused on platelet inhibition therapy. Clopidogrel is a novel thienopyridine inhibitor of adenosine diphosphate-induced platelet activation. Recent studies have shown that in...

Nickel-Catalyzed Reactions Directed toward the Formation of Heterocycles.

Accounts of chemical research

Kurahashi T, Matsubara S.

Acc Chem Res. 2015 Jun 16;48(6):1703-16. doi: 10.1021/acs.accounts.5b00041. Epub 2015 May 19.

Heterocycles have garnered significant attention because they are important functional building blocks in various useful molecules, such as pharmaceuticals, agricultural chemicals, pesticides, and materials. Several studies have been conducted regarding the preparation of heterocyclic skeletons with an emphasis on...

Front Neurol. 2015 Aug 31;6:188. doi: 10.3389/fneur.2015.00188. eCollection 2015.

Valproic acid (VPA) is a widely used antiepileptic drug with a broad range of effects and broad clinical efficacy. As a well-known histone deacetylase (HDAC) inhibitor, VPA regulates epigenetic programming by altering the expression of many genes. The aim...

The stereoselective formation of highly substituted CF3-dihydropyrans as versatile building blocks.

Chemical communications (Cambridge, England)

Donslund BS, Monleón A, Larsen J, Ibsen L, Jørgensen KA.
PMID: 26225818
Chem Commun (Camb). 2015 Sep 14;51(71):13666-9. doi: 10.1039/c5cc04874e.

The highly enantioselective dienamine-mediated formation of 5-bromo-6-(trifluoromethyl)-3,4-dihydro-2H-pyrans from α,β-unsaturated aldehydes and α-bromo-(trifluoromethyl)-enones employing a C2-symmetric aminocatalyst is described. The products are demonstrated to be applicable in coupling reactions directly onto the ring, thereby granting access to a broad scope...

Ceria-Vanadia/Silica-Catalyzed Cascade for C-C and C-O Bond Activation: Green One-Pot Synthesis of 2-Amino-3-cyano-4H-pyrans.

PMID: 27308209
ChemistryOpen. 2015 Aug 19;5(1):38-42. doi: 10.1002/open.201500159. eCollection 2016 Feb.

We designed a ceria-vanadia/silica (Ce-V/SiO2) heterogeneous catalyst and used it for the green and efficient synthesis of 2-amino-3-cyano-4H-pyran derivatives. The green reaction was a multicomponent one-pot condensation of 5,5-dimethylcyclohexane-1,3-dione, aromatic aldehyde, and malononitrile in an eco-compatible solvent (ethanol). The...

BACKGROUND: Quality of labor analgesia plays a vital role in the maternal outcome. Very few literature are available analyzing the quality of epidural labor analgesia.AIM: The aim of this study was to compare the effectiveness of 0.1% levobupivacaine and...

Addition-Rearrangement of Aryl- and Alkoxysulfonyl Isocyanates with 5-Methyl-Substituted 3,4-Dihydro-2-methoxy-2H-pyrans. Selective Synthesis of Functionalized 2-Piperidones(1).

The Journal of organic chemistry

3,4-Dihydro-2-methoxy-5-methyl-2H-pyran and 3,4-dihydro-2-methoxy-5,6-dimethyl-2H-pyran undergo addition-rearrangement reactions with arylsulfonyl isocyanates to generate the corresponding 3-formyl- and 3-acetyl-6-methoxy-3-methyl-1-(arylsulfonyl)-2-piperidones. For example, 3,4-dihydro-2-methoxy-5-methyl-2H-pyran and phenylsulfonyl isocyanate afforded 3-formyl-6-methoxy-3-methyl-1-(phenylsulfonyl)-2-piperidone as a separable trans/cis mixture in high yield. The more reactive phenoxysulfonyl and alkoxysulfonyl isocyanates...
