Enantioselective synthesis of multisubstituted biaryl skeleton by chiral phosphoric acid catalyzed desymmetrization/kinetic resolution sequence.

J. Am. Chem. Soc. 135(10) , 3964-70, (2013)

Described herein is the enantioselective synthesis of multisubstituted biaryl derivatives by chiral phosphoric acid catalyzed asymmetric bromination. Two asymmetric reactions (desymmetrization and kinetic resolution) proceeded successively to afford chiral bi...

Titrimetric determination of acetylenic hyponotics using organic brominating agents.

Pharm. Weekbl. Sci. 10(2) , 90-2, (1988)

A titrimetric method is described for the determination of three acetylenic hypnotics, namely ethchlorvynol, ethinamate, and methylpentynol carbamate, in bulk and in dosage forms. The method involves the use of either 1,3-dibromo-5,5-dimethylhydantoin (DBH), ...

N-bromoimide/DBU combination as a new strategy for intermolecular allylic amination.

Org. Lett. 15(20) , 5186-9, (2013)

Allylic amination reactions of alkenes, with an NBP (N-bromophthalimide) or NBS (N-bromosuccinimide)/DBU combination, were developed, in which both internal and external nitrogen nucleophiles can be installed directly. Dual activation of NBS or NBP by DBU lea...

Colorimetric and titrimetric assay of isoniazid.

J. Pharm. Biomed. Anal. 10(6) , 421-6, (1992)

Two methods are proposed for the determination of isoniazid in pure form or in tablets. In the first method chlorpromazine hydrochloride, when treated with 2-iodoxybenzoic acid as an oxidant in 50% w/v o-phosphoric acid solution, is oxidized to chlorpromazine...

C2-symmetric cyclic selenium-catalyzed enantioselective bromoaminocyclization.

J. Am. Chem. Soc. 135(4) , 1232-5, (2013)

A catalytic asymmetric bromocyclization of trisubstituted olefinic amides that uses a C(2)-symmetric mannitol-derived cyclic selenium catalyst and a stoichiometric amount of N-bromophthalimide is reported. The resulting enantioenriched pyrrolidine products, w...

Site-selective bromination of vancomycin.

J. Am. Chem. Soc. 134(14) , 6120-3, (2012)

We report the site-selective bromination of vancomycin to produce, with substantial efficiency, previously unknown monobromovancomycins, a dibromovancomycin, and a tribromovancomycin. We document the inherent reactivity of native vancomycin toward N-bromophth...

Density functional theory study of the FT-IR spectra of phthalimide and N-bromophthalimide.

Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 62(4-5) , 918-25, (2005)

Fourier transform infrared (FT-IR) spectra of phthalimide and N-bromophthalimide have been recorded in the range of 4000-400 cm-1. With the hope of providing more and effective information on the fundamental vibrations, a normal coordinate analysis has been p...

Titrimetric methods for the determination of some sulpha drugs using N-bromophthalimide and N-bromosaccharin.

Analyst 113(9) , 1369-72, (1988)

Titrimetric determination of para-aminobenzoic acid using N-bromophthalimide and N-bromosaccharin.

J. Pharm. Biomed. Anal. 7(5) , 627-31, (1989)
