Vibrational circular dichroism of 3-(trifluoroacetyl)-camphor and its interaction with chiral amines.

Chirality

Merten C, Jalkanen KJ, Weiss VC, Hartwig A.
PMID: 20186758
Chirality. 2010 Aug;22(8):772-7. doi: 10.1002/chir.20832.

Vibrational circular dichroism (VCD) spectroscopy and density functional theory (DFT) calculations are used to investigate the keto-enol equilibrium of 3-(trifluoroacetyl)-camphor (TFC) and to study the interaction of TFC with chiral amines in deuterated Chloroform. It is shown that the...

Linear-selective hydroarylation of unactivated terminal and internal olefins with trifluoromethyl-substituted arenes.

Journal of the American Chemical Society

Bair JS, Schramm Y, Sergeev AG, Clot E, Eisenstein O, Hartwig JF.
PMID: 25171744
J Am Chem Soc. 2014 Sep 24;136(38):13098-101. doi: 10.1021/ja505579f. Epub 2014 Sep 15.

We report a series of hydroarylations of unactivated olefins with trifluoromethyl-substituted arenes that occur with high selectivity for the linear product without directing groups on the arene. We also show that hydroarylations occur with internal, acyclic olefins to yield...

Adsorption mechanism and valency of catechol-functionalized hyperbranched polyglycerols.

Beilstein journal of organic chemistry

Krysiak S, Wei Q, Rischka K, Hartwig A, Haag R, Hugel T.
PMID: 26150898
Beilstein J Org Chem. 2015 May 18;11:828-36. doi: 10.3762/bjoc.11.92. eCollection 2015.

Nature often serves as a model system for developing new adhesives. In aqueous environments, mussel-inspired adhesives are promising candidates. Understanding the mechanism of the extraordinarily strong adhesive bonds of the catechol group will likely aid in the development of...

Lung transplantation at Duke.

Journal of thoracic disease

Gray AL, Mulvihill MS, Hartwig MG.
PMID: 27076968
J Thorac Dis. 2016 Mar;8(3):E185-96. doi: 10.21037/jtd.2016.02.08.

Lung transplantation represents the gold-standard therapy for patients with end-stage lung disease. Utilization of this therapy continues to rise. The Lung Transplant Program at Duke University Medical Center was established in 1992, and since that time has grown to...

Chemoselective, Enzymatic C-H Bond Amination Catalyzed by a Cytochrome P450 Containing an Ir(Me)-PIX Cofactor.

Journal of the American Chemical Society

Dydio P, Key HM, Hayashi H, Clark DS, Hartwig JF.
PMID: 28080030
J Am Chem Soc. 2017 Feb 08;139(5):1750-1753. doi: 10.1021/jacs.6b11410. Epub 2017 Jan 26.

Cytochrome P450 enzymes have been engineered to catalyze abiological C-H bond amination reactions, but the yields of these reactions have been limited by low chemoselectivity for the amination of C-H bonds over competing reduction of the azide substrate to...

Feasibility of halogen determination in noncombustible inorganic matrices by ion chromatography after a novel volatilization method using microwave-induced combustion.

Talanta

Pereira RM, Costa VC, Hartwig CA, Picoloto RS, Flores EM, Duarte FA, Mesko MF.
PMID: 26592579
Talanta. 2016 Jan 15;147:76-81. doi: 10.1016/j.talanta.2015.09.031. Epub 2015 Sep 13.

A microwave-induced combustion (MIC) system based on the volatilization process was applied for subsequent halogen determination from noncombustible inorganic matrices. Portland cement samples were selected to demonstrate the feasibility of the proposed method, allowing the subsequent determination of Cl...

Photoejection of one CO ligand from isolated CpM(CO)n+1BR2 (n = 1: M = Fe, Ru; n = 2: M = Mo,W; R2 = catecholate or pinacolate) compounds produces a coordinatively unsaturated 16 e- intermediate, a cyclic dioxaboryl transition metal...

PMID: 16667124
Plant Physiol. 1989 Nov;91(3):1138-42. doi: 10.1104/pp.91.3.1138.

Alfalfa (Medicago sativa L.) seeds and roots can create complex rhizosphere effects by releasing flavonoids that induce nodulation (nod) genes in Rhizobium meliloti. Previous reports identified luteolin and 4,4'-dihydroxy-2'-methoxychalcone as strong inducers that are released from seeds and roots,...
