Electrochemical reduction ofN-Boc-α-aminosulfones in DMF using an undivided cell equipped with a Pt plate cathode and an Mg rod anode under atmospheric pressure of bubbling carbon dioxide through the solution under constant current conditions resulted in a reductive C-S bond cleavage with elimination of benzenesulfinate ion generating the corresponding anion species followed by fixation of carbon dioxide to give the correspondingN-Boc-α-amino acids in moderate to good yields.

experimental part, p. 2159 - 2168 (2012/06/01)
Incorporation reactions of carbon dioxide (CO2) with N-Boc-α-amido and α-acetoxy stannanes were developed using CsF as a mild tin activator. Monoprotected α-amido stannanes could be used, and the corresponding arylglycine derivatives were obtained in moderate-to-high yields under 1 MPa (10 atm) of CO2 pressure. α-Acetoxy stannanes also underwent carboxylation to afford mandelic acid derivatives in excellent yields under ambient CO2 pressure. Both transformations enabled the synthesis of α-tertiary and α-quaternary carboxylic acid derivatives. In addition, the chirality of (S)-N-tert-butylsulfonyl-α- amido stannanes was transferred with up to 90% inversion of configuration at 100 °C.

Molecular modeling and inhibitory potencies of tetrapeptide protease inhibitors of HCV NS3 proposed phenylglycine as a new promising P2 residue. The results suggest that phenylglycine might be capable of interacting with the NS3 (protease-helicase/NTPase)

L- and DL-isomers of compounds of the formula STR1 and the pharmaceutically acceptable salts thereof, wherein R is hydrogen or methyl; R1 is alkynyl, alkenyl or cycloalkyl, each having from three to seven carbon atoms or alkyl having from one to six carbon atoms which may optionally be substituted by one or more groups selected from hydroxy, alkoxy, carboxy, amino, monoalkylamino, dialkylamino, phenyl and phenoxy, any such phenyl or phenoxy being optionally substituted with one or more hydroxy, alkyl or alkoxy groups, said alkyl and alkoxy optional substituents having from one to six carbon atoms; provided that R1 is other than 4-hydroxy-α-carboxybenzyl or 4-methoxy-α-carboxybenzyl. Said compounds are useful in treating diseases and conditions characterized by reduced blood flow, oxygen availability or carbohydrate metabolism in the cardiovascular system. The D-isomers of the compounds of formula (II) are substantially inactive in treating such diseases and conditions.
