Bakers’ yeast reduction of α-substituted or β,β-disubstituted α,β-unsaturated ketones gave saturated chiral ketones with excellent optical purity, while the β,β-disubstituted derivative remained intact.
The present invention relates to a pharmaceutical composition of oligopeptides, preferably cyclic oligopeptides, said composition further comprising one or more lipophilic and/or amphiphilic compounds, in the presence or absence of water as the main ingredients, the use of the lipophilic and/or amphiphilic compounds for making pharmaceutical compositions of said oligopeptides, and methods of making said pharmaceutical composition.
