A series of N-(acridin-9-yl)-4-(benzo[d]imidazol/oxazol-2-yl) benzamides has been synthesized by the condensation of 9-aminoacridine derivatives with benzimidazole or benzoxazole derivatives. Condensation of 2-hydroxy naphthaldehyde with functionalized diamines leads …

Strain-promoted oxidative annulation of arynes and cyclooctynes with benzamides: palladium-catalyzed C-H/N-H activation for the synthesis of N-heterocycles.

Organic letters

PMID: 25275617
Org Lett. 2014 Oct 17;16(20):5354-7. doi: 10.1021/ol5025426. Epub 2014 Oct 02.

Strained alkynes include arynes and cyclooctynes reacted with N-methoxyamides through palladium-catalyzed C-H/N-H activation for the first time. A variety of important N-heterocycles such as phenanthridinones and isoquinolones were constructed in one step with high efficiency.

Copper-Catalyzed Intramolecular Benzylic C-H Amination for the Synthesis of Isoindolinones.

The Journal of organic chemistry

Yamamoto C, Takamatsu K, Hirano K, Miura M.
PMID: 27504671
J Org Chem. 2016 Sep 02;81(17):7675-84. doi: 10.1021/acs.joc.6b01393. Epub 2016 Aug 18.

A copper-catalyzed intramolecular amination occurs at the benzylic C-H of 2-methylbenzamides to deliver the corresponding isoindolinones of great interest in medicinal chemistry. The mild and abundant MnO2 works well as a terminal oxidant, and the reaction proceeds smoothly under...

Traditionally, cyanobacterial activity in oceanic photic layers was considered responsible for the marine pelagic dinitrogen (N

Consensus on the solubility of NaCl in water from computer simulations using the chemical potential route.

The Journal of chemical physics

Benavides AL, Aragones JL, Vega C.
PMID: 27036458
J Chem Phys. 2016 Mar 28;144(12):124504. doi: 10.1063/1.4943780.

The solubility of NaCl in water is evaluated by using three force field models: Joung-Cheatham for NaCl dissolved in two different water models (SPC/E and TIP4P/2005) and Smith Dang NaCl model in SPC/E water. The methodology based on free-energy...

Copper-Mediated Oxidative Coupling of Benzamides with Maleimides via Directed C-H Cleavage.

Organic letters

Miura W, Hirano K, Miura M.
PMID: 26226391
Org Lett. 2015 Aug 21;17(16):4034-7. doi: 10.1021/acs.orglett.5b01940. Epub 2015 Jul 30.

A Cu(OAc)2/Cy2NMe-mediated oxidative direct coupling of benzamides with maleimides has been developed. The aromatic C-H alkenylation with the aid of an 8-aminoquinoline-based bidentate directing group is followed by an intramolecular aza-Michael-type addition to form the isoindolone-incorporated spirosuccinimides, which are...

Effect of Fodder Tree Species with Condensed Tannin Contents on In vitro Methane Production.

Asian-Australasian journal of animal sciences

PMID: 26732330
Asian-Australas J Anim Sci. 2016 Jan;29(1):73-9. doi: 10.5713/ajas.15.0464.

The objective was to evaluate the effect of fodder tree species (FTS) with condensed tannin contents: Cordia elaeagnoides, Platymiscium lasiocarpum, Vitex mollis, and Haematoxylon brasiletto, on in vitro methane (CH4) production at 24 h post incubation. The analysis was...

Ruthenium(II)-Catalyzed C-H Oxygenations of Reusable Sulfoximine Benzamides.

Organic letters

C-H oxygenations of synthetically meaningful sulfoximine benzamides were accomplished by a versatile ruthenium catalysis regime. The ruthenium(II) catalyst was characterized by excellent mono- and chemoselectivity as well as positional selectivity via facile base-assisted intramolecular electrophilic substitution-type (BIES) C-H activation....
