A facile synthesis of 2-methyl-[3,4-di-O-acetyl-6-O-(chloroacetyl)-1,2-dideoxy-alpha-D-glucopyrano]-[2',1':4,5]-2-oxazoline.

K L Matta et al.

Carbohydrate research, 51(2), 215-222 (1976-11-01)

The use of the chloroacetyl group as a protecting group has been studied for a 2-methylglyco-[2',1':4,5]-2-oxazoline. The reaction of chloroacetyl chloride or chloroacetic anhydride with 2-acetamido-1,3,4-tri-O-acetyl-2-deoxy-beta-D-glucopyranose provided 2-acetamido-1,3,4-tri-O-acetyl-6-O-(chloroacetyl)-2-deoxy-beta-D-glucopyranose which, on treatment with anhydrous ferric chloride in dichloromethane, produced the desired

Preparation of enantiomerically pure L-7-azatryptophan by an enzymatic method and its application to the development of a fluorimetric activity assay for tryptophanyl-tRNA synthetase.

J D Brennan et al.

Analytical biochemistry, 252(2), 260-270 (1997-11-05)

The reaction of D,L-7-azatryptophan (D,L-7AW) with tryptophanyl-tRNA synthetase (TrpRS), adenosine triphosphate (ATP), and Mg2+ in the presence of inorganic pyrophosphatase results in the formation of a highly fluorescent l-7AW-adenylate complex. Detection of this complex is based on its enhanced fluorescence

Synthesis of 3,3'-bis(sulfonato)-4,4'-bis(chloroacetamido)azobenzene and cysteine cross-linking for photo-control of protein conformation and activity.

Darcy C Burns et al.

Nature protocols, 2(2), 251-258 (2007-04-05)

This protocol describes a procedure for the synthesis of 3,3'-bis(sulfonato)-4,4'-bis(chloroacetamido)azobenzene (BSBCA), a water-soluble, thiol-reactive, photo-switchable cross-linker. In addition, a protocol is outlined for installing the cross-linker in an intramolecular fashion onto proteins bearing two surface-exposed Cys residues. BSBCA is designed
