N-Bromosuccinimide cleavage of a lysine-rich histone fraction (histone III-S) yields a peptide substrate, purified by reverse-phase h.p.l.c., for the Ca2+ + phospholipid-dependent protein kinase (protein kinase C). This substrate displays no reactivity with the cyclic AMP-dependent protein kinase, and may prove useful for the detection of protein kinase C activity in crude tissue extracts.

The first synthesis of the furan-containing snyderane, (+)-luzofuran, is reported. The key step in this approach was an electrophilic brominative cyclization, which was accomplished using a nucleophilic N-heterocycle-flanked phosphoramidite catalyst in combination with the common laboratory reagent N-bromosuccinimide.

An efficient and practical method for the synthesis of indolyl-nitroalkane derivatives catalyzed by N-bromosuccinimide is described. The generality of this method was demonstrated by synthesizing an array of diverse 3-substituted indole derivatives by the reaction of different beta-nitrostyrenes with various substituted indoles. Simple reaction conditions accompanied by good yields of indolyl-n...

A combination of mandelic acid and N-bromosuccinimide efficiently converts prochiral alkenes into a readily separable 1:1 mixture of the bromomandelates. The diastereomerically pure bromomandelates are then converted into a variety of enantiomerically pure products. Terminal alkenes are converted into enantiomerically pure epoxides. Cyclohexene is converted into enantiomerically pure cis-2-azid...

A new bicyclic sulfonamide derivative, N-(1-(bromomethyl)-7,7-dimethylbicyclo[2.2.1]heptan-2-yl)benzenesulfonamide, was synthesized in the reaction of benzenesulfonamide and camphene presence N-bromosuccinimide acetonitrile. The proposed mechanism investigated involves Wagner–Meerwein rearrangement stage. 3-(Bromomethylene)-2,2-dimethylbicyclo[2.2.1]heptane isolated as a minor product. products...

The amino acid sequence has been determined for the first 72 residues of a lysine-rich histone from rabbit thymus. These are the residues contained in a fragment released from the histone by treatment with N-bromosuccinimide. Peptides derived by tryptic, thermolysin, and chymotryptic digestion of this 72-residue fragment were used to reconstruct the total sequence. Analysis of the sequence reve...

Equations are presented by which potential-volume data from redox titrations can be analyzed. Mixtures of analytes as well as of titrants may be analyzed, yielding for each component its concentration, number of electrons, and reduction potential. A novel weighting function ensures endpoint accuracy in fitting. Standard deviation of each parameter is obtained. The equations can be readily imple...
