of fluoride ion. The application of this strategy by using chiral catalysts leads to a new enantioselective total synthesis of natural cis-pterocarpans and their trans isomers. Through this method, the first enantioselective total synthesis of the antifungal agent (-)-pterocarpin was achieved. In addition, a new entry into the heteroaromatic system of 2,5-dihydrobenzoxepine is also presented.

The invention relates to a cosmetic, dermatological or pharmaceutical preparation, containing one, two or more compounds of formula (I) and/or a pharmaceutically acceptable salt of a compound of this type,
(i) for use in a method for preventing, treating or reducing cellulite, and/or
(ii) in an adequate quantity
to reduce the lipid quantity contained in subcutaneous fat tissue, and/or
to inhibit the differentiation of preadipocytes, and/or
to inhibit the lipogenesis in adipocytes,
wherein the radicals R1 to R8, independently of one another, signify hydrogen, hydroxy or C1-C4-alkoxy, and/or two adjacent radicals together form a methylenedioxy group.

The present invention relates to the technical field of medicine, and relates specifically to a method for dissolving a flavonoid compound, a carbon glycoside compound, or a stilbene compound and a method for preparing an injection or a powder for injection. The method: the flavonoid compound, the carbon glycoside compound, or the stilbene compound is mixed with a solubilizer to acquire a reactant; when water for injection is heated and stirred in a vacuum, the reactant is added under the protection of nitrogen or argon to acquire a product. The dissolution speed of the method is fast, redissolution tests show that a freeze-dried powder that is acquired when a water-soluble medicament acquired is freeze-dried can dissolve completely in just five seconds, a significant increase in redissolution speed compared with a control group; also, the stability is great, and a medicinal requirement for clinical emergencies is satisfied.
