Diastereoselective formation of a dicopper(i) helicate with a chiral tetradentate pyridylthiazole ligand.

Chem. Commun. (Camb.) (15) , 1999-2001, (2009)

Reaction of a pinene-based pyridylthioamide with 1,4-dibromo-2,3-butanedione in refluxing methanol yielded a new chiral pyridylthiazole ligand L which forms a dinuclear double-stranded helicate with Cu(i) ions; this helicate has opposite helical chirality whe...

Cysteinyl peptides labeled by dibromobutanedione in reaction with rabbit muscle pyruvate kinase.

Protein Sci. 1(5) , 678-87, (1992)

The bifunctional reagent 1,4-dibromobutanedione (DBBD) reacts covalently with pyruvate kinase from rabbit muscle to cause inactivation of the enzyme at a rate that is linearly dependent on the reagent concentration, giving a second order rate constant of 444 ...
