Hydrodebromination of allylic and benzylic bromides was successfully achieved by a rhodium porphyrin complex catalyst using water as the hydrogen source without a sacrificial reductant. Mechanistic investigations suggest that bromine atom abstraction via a rhodium porphyrin metalloradical operates to give the rhodium porphyrin alkyl species and the subsequent hydrolysis of the rhodium porphyrin alkyl species to a hydrocarbon product is a key step to harness the hydrogen from water.
Enzyme-catalyzed synthesis of optically pure β-sulfonamidopropionic acids. Useful starting materials for P-3 site modified renin inhibitors

, p. 435 - 438 (2007/10/02)
The novel and efficient of several racemic β-sulfonamidopropionate esters is described. Treatment of the racemic esters with Chymotrypsin or Subtilisin Carlsberg (purified of detergent grade) provided the corresponding (S)-carboxylic acids in 60-90% yield
Necic Acid Synthons. Part 2. Regioselectivity in the Reactions of (Z)-2-Bromomethyl-2-alkenoate Esters with Selected Carbon Nucleophiles

, p. 2293 - 2295 (2007/10/02)
The preparation of selected (Z)-2-bromomethyl-2-alkenoate esters and their subsequent reaction with acetoacetic ester-derived nucleophiles is described.Both the substrate structure and the solvent system have significant effects on the regioselectivity of these nucleophilic displacements.
