‘Sugaring’ carbosilane dendrimers via hydrosilylation

Two new pathways to introduce carbohydrate derivatives into dendritic carbosilane structures were explored. Pathway one utilised alcoholysis of a chlorosilane with a protected hydroxyethyl glycoside resulting in Si–O linkages. Pathway two proceeds via a hydrosilylation reaction of a protected allyl glycoside with a carbosilane containing Si–H end groups in the presence of a platinum catalyst, thus leading to Si–C linked structures.
