    Abstract: The present invention relates to a method for obtaining crystalline 2'-fucosyllactose from a 2'-FL raw material, which contains 2'-FL as a main constituent and at least 0.5% by weight, frequently at least 1% by weight, in particular at least 2% by weight, more particularly at least 5% by weight, and especially at least 8% by weight,based on the total amount of mono-and oligosaccharides in the raw material, of one or more mono- or oligosaccharides different from 2'-FL, where the method comprises a)providing a solution of the 2'-FL raw material in water, which does not contain more than 10% by weight, preferably not more than 7% by weight, more preferably not more than 5% by weight of organic solvents, based on the total amount of water; b) effecting the crystallization of 2'-FL from the solution provided in step a) by inducing conditions of a controlled super saturation in the solution; and c) separating crystalline 2'-FL from the mother liquor, and where during controlled supersaturation in step b) not more than 10% by weight, preferably not more than 7% by weight, more preferably not more than 5% by weight of organic solvents are present, based on the total amount of water present during step b).

    Abstract: The present invention relates to the preparation of oxovinylionol and its O-protected derivatives of the formula I (I) in which R is hydrogen or an OH protecting group, for example a group Si(Ra)3 by reacting a compound of the formula II (II) in which R have the meanings given above for formula I, i.e. ?-vinyl ionol (formula II, R = hydrogen) or an O-protected derivative thereof (formula II, R = OH protecting group) with an oxidant in the presence of at least one transition metal, where the oxidant comprises at least one oxygen-containing compound which is selected from among hydrogen peroxide and organic hydroperoxides.
