摘要:Subject of the invention is a method for enantioselective production of an isoflavane from an isoflavone, comprising the steps: (a) selectively reducing the isoflavone, such that the 4-keto group of the isoflavone is converted to a 4-hydroxy group, and the 2,3-double bond of the isoflavone is converted to a 2,3-single bond, thereby obtaining a 4-hydroxy intermediate, and (b) reacting the 4-hydroxy intermediate with a chiral reagent, such that a chiral group is covalently attached to the C4-position of the 4-hydroxy intermediate, thereby obtaining a chiral intermediate. The invention also relates to intermediates of formulae (IV), (V), (VI) and (VII) obtainable in the inventive process.

摘要:Subject of the invention is a method for the production of isoflavanes from isoflavones, whereby in a first reaction step (a) the 4-keto group of the isoflavone is reduced in a enantioselective manner, whilst the 2,3-double bond is maintained, to the 4-hydroxy compound.

摘要:The invention is related to compositions and methods that naturally protect plant tissues against ultraviolet radiation and temperature, thus giving protection against sunburn to plants, plant parts, fruits and/or flowers during their development. The invention is also related to compositions and methods to naturally improve the color of plants, plant parts, fruits and/or flowers by inducing the natural synthesis of flavonoids and anthocyanins present in plants. Likewise, the present invention is directed to improving the nutritional value of plants, plant parts, fruits and/or flowers by increasing the normal levels of polyphenolic compounds, especially flavonoids, present therein. Additionally, the present invention is related to compositions and methods that give more resistance to plants, plant parts, fruits and/or flowers against pathogens as bacteria and fungi. Finally, the present invention is related to plants, plant parts, fruits, flowers and/or propagating material treated with the compositions described in the present document.

摘要:The invention relates to topical cosmetic or dermatological compositions for the treatment of mature or intrinsically or extrinsically aged skin, in particular, for anti-wrinkle treatment, containing a combination of at least two selected peptides in a suitable cosmetic or dermatological vehicle, which have an effect at differing points of the process of collagen and/or fibronectin synthesis.
