The lithium diorganocuprate reactions with L-serine derivatives are studied. Retention of configuration, or at least a high enantiomeric excess (>80%) of the formed α-amino esters is observed in all cases. Attempts are made to restrict side-reactions.
The invention relates to nonadepsipeptides and methods for their preparation and their use for the production of medicaments for the treatment and/or prophylaxis of diseases, in particular bacterial infectious diseases.
The present invention provides cyclic depsipeptide compounds of formula (I) and compositions comprising the compounds that are effective against parasites that harm animals. The compounds and compositions may be used for combating parasites in or on mammals and birds. The invention also provides for an improved method for eradicating, controlling and preventing parasite infestation in birds and mammals.
