Abstract:
L'invention concerne une technique de préparation d'organozinciques aromatiques et une composition pour ce faire. Cette composition constitue un réactif susceptible de réaliser la synthèse d'organozinciques et comporte un sel de cobalt, un sel de zinc, un solvant aprotique polaire et du zinc élémentaire sous forme divisée, le zinc élémentaire se trouvant sous la forme solide, les autres éléments étant sous une forme dissoute dans le solvant. Application à la synthèse organique.
Abstract:
The present invention concerns compounds of the following formula (I) or a pharmaceutically acceptable salt thereof, a stereoisomer or a mixture of stereoisomers in any proportion, in particular a mixture of enantiomers, and particularly a racemate mixture, in which R represents H, OH or OR 19 , as well as processes for preparing these compounds and their use as inducer for the transcription of genes under control of the lac promoter.
Abstract:
The present invention relates to compounds of formula (I): or a pharmaceutically acceptable salt thereof, a tautomer, a stereoisomer or a mixture of stereoisomers in any proportion, in particular a mixture of enantiomers, and particularly a racemate mixture, as well as to their process of preparation, their use in the peptide synthesis, said peptide and the use of said peptide.
