Atropisomerism in linear tetrapyrroles

, p. 7411 - 7421 (2007/10/03)
Novel bilirubin and biliverdin congeners with propionic acids replaced by o-carboxyphenyl exhibit diastereomerism due to axial chirality about the carbon-carbon single bond linking the o-carboxyphenyl group to a pyrrole ring. Evidence for atropisomerism was found even in the monopyrrole precursor, ethyl 3,5-dimethyl-4-(o-carboxyphenyl)pyrrole-2-carboxylate. Like bilirubin, o-carboxyphenyl rubin 1a adopts an intramolecularly hydrogen-bonded ridge-tile conformation in nonpolar solvents. In solutions containing optically active amines or human serum albumin 1a exhibits intense bisignate exciton coupling-type induced circular dichroism for its long wavelength absorption near 400nm.
The Hurtley reaction III. A reactivity study of copper(I) 2-halobenzoates either as pure reagents, or under Hurtley reaction conditions, and as a part of mixed (benzoato)(mesityl)copper(I) clusters

The reactivity of pure isolated copper(I) 2-halobenzoates has been studied at 20 and 80 deg C either with or without oxidizing agents (O2 and CuBr2).Furthermore, these complexes have been reacted at 80 deg C either alone or in combination with sodium acet
