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.

Various Baylis–Hillman–derived new N-allylated 2-nitroiminoimidazolidine analogs were efficiently prepared using potassium carbonate as base. Simple workup procedure, excellent yields, and mild reaction conditions are the salient features of this method. All the synthesized compounds are screened for their larvicidal activity on fourth instar mosquito larvae, Culex quinquefasciatus.
Enzyme-catalyzed synthesis of optically pure β-sulfonamidopropionic acids. Useful starting materials for P-3 site modified renin inhibitors
Mazdiyasni, Hormoz,Konopacki, Donald B.,Dickman, Daniel A.,Zydowsky, Thomas M.
, 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
NOVEL PHENYLALANINE ANALOGUES AS PUTATIVE INHIBITORS OF ENZYMES ACTING ON PHENALALANINE

, p. 711 - 714 (2007/10/02)
Two analogues of phenylalanine, (+/-)-2-aminomethyl-3-phenylpropanoic acid and (E)-2-aminomethyl-3-phenylpropenoic acid, were synthesized and found to inhibit buckwheat phenylalanine ammonia-lyase (PAL) competitively with Ki values of 16.5 and
Necic Acid Synthons. Part 2. Regioselectivity in the Reactions of (Z)-2-Bromomethyl-2-alkenoate Esters with Selected Carbon Nucleophiles
Ameer, Farouk,Drewes, Siegfried E.,Emslie, Neville D.,Kaye, Perry T.,Mann, R. Leigh
, 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.
