A selective dehydrogenation boron methyl catalyzes the reaction of the new method (by machine translation)

The invention relates to ruthenium catalytic ester derivative selective dehydrogenation boron reaction new method, including falling to six coordination of borneol diene (NBD) ligand of ruthenium complex as catalyst, in order to methyl ester derivatives and joint frequency which mellow boron ester is the reaction substrate, the reaction under mild conditions, the high-efficient catalytic ester derivative in an oxygen atom ortho-methyl-hydrogen bond selectively generating boron reaction, to obtain the corresponding methyl ester borate product. At present, in the ester derivatives on the oxygen atom ortho-methyl hydrogen bond of boron selective dehydrogenation reaction has not yet been reported. The invention realized for the first time the occurrence of the oxygen atom of the ester derivative selective ortho-methyl of the dehydrogenation boron reaction, as the organic ester borate such organic synthetic intermediates preparation provides a new response strategies.

Decarbonylative Methylation of Aromatic Esters by a Nickel Catalyst

A Ni-catalyzed decarbonylative methylation of aromatic esters was achieved using methylaluminums as methylating agents. Dimethylaluminum chlorides uniquely worked as the methyl source. Because of the Lewis acidity of aluminum reagents, less reactive alkyl esters could also undergo the present methylation. By controlling the Lewis acidity of aluminum reagents, a chemoselective decarbonylative cross-coupling between alkyl esters and phenyl esters was successful.

Evidence for an Important 13C NMR Shielding Effect for Carbon Atoms Bearing a Heavy Chalcogen Substituent

An important 13C NMR shielding effect on carbons bearing a heavy chalcogen is demonstrated.This effect is parallel to that induced by iodine, but to a lesser extent.For acyclic compounds and for partially saturated heterocycles, there is an excellent linear correlation between the 13C chemical shifts of carbons bearing a chalcogen and carbons bearing a halogen atom in the corresponding compound.The linearity of the relationship is less satisfactory with heteroaromatic compounds.

Thermolysis of Thiophenedicarboxylic Acid Anhydrides as a Route to Five-Membered Hetarynes

Flow vacuum thermolysis (FVT) of the anhydrides of thiophene-2,3- (5) and -3,4-dicarboxylic acid (6) and of thianaphthene-2,3-dicarboxylic acid (7) in the presence of thiophene, 1,3-cyclohexadiene, or benzene gave thianthrene (15a), presumably by aromatization of an intermadiate Diels-Alder adduct of the diene traps and the aryne 2,3-didehydrothiophene (8).A similar rationale explains the formation of dibenzothiophene from 7 and thiophene, the four monomethylthianaphthenes 22-25 from 5 and cyclopentadiene, 5,6-dimethylthianaphthene (15f) from 5 and 2,3-dimethylbutadiene, and a mixture of hydroxythianaphthenes (15d) from 5 and furan.The latter reaction also produces a mixture of isomeric cyclopentanothiophenes (19) which probably arise by decarbonylation of 15d.An FVT reaction of 5 with propyne as the trap gave a mixture of allenyl-(28) and propynylthiophenes 29 which probably arise by an ene reaction of the trap and the aryne 8.Decomposition of the anhydrides 5 and 6 in molten anthracene led only to Friedel-Crafts products such as thienylanthracenes 33 and quinones 34 from 5 and 39 and 40 from 6.The diene reactivity of thiophene 13a in the gas phase was demonstrated by the formation of naphthalene from its reaction with benzyne generated from the thermolysis of indanetrione and by the formation of indene from 13a plus cyclopentadiene.Possible, but improbable, interpretations of the FVT results without invoking a five-membered hetaryne intermediate are considered.

Palladium-catalyzed hydroxylation of aryl and heteroaryl halides enabled by the use of a palladacycle precatalyst

A method for the hydroxylation of aryl and heteroaryl halides, promoted by a catalyst based on a biarylphosphine ligand tBuBrettPhos (L5) and its corresponding palladium precatalyst (1), is described. The reactions allow the cross-coupling of both potassium and cesium hydroxides with (hetero)aryl halides to afford a variety of phenols and hydroxylated heteroarenes in high to excellent yield.

1,3-Disubstituted benzazepines as novel, potent, selective neuropeptide Y Y1 receptor antagonists

A novel series of potent and selective non-peptide neuropeptide Y (NPY) Y1 receptor antagonists, having benzazepine nuclei, have been designed, synthesized, and evaluated for activity. Chemical modification of the R1 and R3 substituents in structure 1 (Chart 1) yields several compounds that show high affinity for the Y1 receptor (K(i) values of less than 10 nM). SAR studies revealed that introduction of an isopropylurea group at R1 and a 3- (benzo-condensed-urea) group, 3-(fluorophenylurea) group, or a 3-(N-(4- hydroxyphenyl)guanidine) group at R3 in structure 1 afforded potent and subtype-selective NPY Y1 receptor antagonists. 3-(3-(Benzothiazol-6- yl)ureido)-1-N-(3-(N’-(3-isopropylureido))benzyl)-2,3,4,5-tetrahydro-1H-1- benzazepin-2-one (21), which was one of the most potent derivatives, competitively inhibited specific [125I]peptide YY (PYY) binding to Y1 receptors in human neuroblastoma SK-N-MC cells (K(i) = 5.1 nM). 21 not only inhibited the Y1 receptor-mediated increase in cytosolic free Ca2+ concentration in SK-N-MC cells but also antagonized the Y1 receptor-mediated inhibitory effect of peptide YY on gastrin-induced histamine release in rat enterochromaffin-like cells. 21 showed no significant affinity in 17 receptor binding assays including Y2, Y4, and Y5 receptors.
