Les groupes anioniques et nucleophiles sur la chaine laterale des ylures de triphenylphosphonium provoquent un deplacement de la stereochimie de l'alcene obtenu vers l'isomere trans dans les reactions avec des aldehydes. L'effet est souvent plus important avec des aldehydes aromatiques qu'avec des aldehydes aliphatiques. Les substituants etudies sont les groupes oxydo, carboxylate, amino et amido

A new series of omega-disubstituted alkenoic acid derivatives derived from samixogrel 5 were designed and synthesized as combined thromboxaneA2receptorantagonists/thromboxaneA2 synthase inhibitors with improved solubility and reduced protein binding compared to 5. Hexenoic acid derivatives with a 3-pyridyl group and 3-(2-cyano-3-alkyl-guanidino)phenyl substituent were found to be optimal with regard
The present invention relates generally to amino acid derivatives and to methods of making the same. In particular, the invention relates to compounds bearing a stereochemical identity, that is, the same stereochemistry, with the chiral &agr;-carbon of D-&agr;-amino acids and their use in methods of therapy, including the treatment of inflammatory diseases, and to compositions and enantiomeric mixtures containing them.
