Summary of "Theoretical Explanation of Reaction Site Selectivity in the Addition of a Phenoxy Group to Perfluoropyridine."

Pentafluoropyridine, a potentially useful precursor in organofluorine methodology, undergoes selective substitution of a fluorine with a phenoxide at the site para to the nitrogen. Subsequent aryloxide substitutions can be accomplished at the ortho positions with aryloxide groups containing various functional groups para to the phenoxide oxygen. During this phase of the reaction, "reverse reactions" involving substitutions of the original para substituent with a free fluoride or with another aryloxide moiety are observed with a frequency that depends on the functional group para to the oxy-gen on the aryloxide. Herein, we provide a theoretical explanation of these observations through use of density functional theory.

Palladium-Catalyzed Site-Selective C(sp)-H Arylation of Phenylacetaldehydes.

We describe a Pd-catalyzed selective C-H arylation reaction of phenylacetaldehydes using l-valine as the transient directing group. This process showed a broad substrate scope and excellent selectivit...

meta C-H Arylation of Electron-Rich Arenes: Reversing the Conventional Site-Selectivity.

Controlling site-selectivity of C-H activation without using a directing group remains a significant challenge. While Pd(Ⅱ) catalysts modulated by a mutually repulsive pyridine type ligands have bee...

The effect of chiral N-substituents with methyl or trifluoromethyl groups on the catalytic performance of mono- and bifunctional thioureas.

We evaluated thiourea organocatalysts that incorporate a chiral group which includes a trifluoromethyl moiety and contrasted their performance with non-fluorinated analogs. The comparison between such...

Reaction of threonine synthase with the substrate analogue 2-amino-5-phosphonopentanoate: Implications into the proton transfer at the active site.

Threonine synthase catalyzes the conversion of O-phospho-L-homoserine and a water molecule to L-threonine and has the most complex catalytic mechanism among the pyridoxal 5'-phosphate-dependent enzyme...

Synthesis of 2,2,5-Trisubstituted 2-Pyrroles and 2,3,5-Trisubstituted 1-Pyrroles by Ligand-Controlled Site-Selective Dearomative C2-Arylation and Direct C3-Arylation.

Palladium-catalyzed site-selective dearomative C2-arylation of 2,5-diaryl-1-pyrroles with aryl chlorides was accomplished, and a series of 2,2,5-triaryl-2-pyrroles were synthesized. In addition, the s...

Medical and Biotech [MESH] Definitions

Adverse reactions that occur initially at the site of injection or infusion. Milder type is confined to a local allergic flare reaction. A more severe reaction is caused by extravasation of VESICANTS from the blood vessel at the site of injection and can cause damage to the surrounding tissue. In tumor flare reaction symptoms involve well beyond the injection site such as an increase in the tumor size and tumor markers levels, bone pain, and HYPERCALCEMIA.

The covalent bonding of an alkyl group to an organic compound. It can occur by a simple addition reaction or by substitution of another functional group.

Addition of methyl groups to DNA. DNA methyltransferases (DNA methylases) perform this reaction using S-ADENOSYLMETHIONINE as the methyl group donor.

A reaction characterized by a violet color upon the addition of copper sulfate to all compounds with two amide or peptide bonds linked directly or through an intermediate carbon atom. Used in the detection and estimation of proteins and peptides having more than two amino acids.

A theoretical representative nucleotide or amino acid sequence in which each nucleotide or amino acid is the one which occurs most frequently at that site in the different sequences which occur in nature. The phrase also refers to an actual sequence which approximates the theoretical consensus. A known CONSERVED SEQUENCE set is represented by a consensus sequence. Commonly observed supersecondary protein structures (AMINO ACID MOTIFS) are often formed by conserved sequences.
