Abstract:
The invention relates to a continuous flow process for the photoconjugation of chemical entities selected from the group comprising carbohydrates, including mono-, oligo- and polysaccharides, amino acids, peptides and proteins, unbranched and branched oligomers and polymers, including dendrimers, which process comprises at least the following steps: a) providing a mixture of the reactants dissolved in an aqueous or organic solvent; b) passing said mixture through a continuous flow reactor and concomitantly irradiating the mixture with light in order to initiate and perform the photoreaction. In preferred embodiments, the photoconjugation is a thiol-ene conjugation or a [2+2] cycloaddition. A further aspect of the invention relates to the conjugates obtainable by this continuous flow process, in particular dendronized polymers such as carbohydrate-dendronized polymers.
