This work describes our preliminary efforts towards the development of aryl glucuronides as potential probes for heparanase. During the course of these initial investigations, attempted glycosidation of methyl 2,3,4-tri-O-acetyl-alpha-D-glucopyranosyluronate trichloroacetimidate with 4-hydroxycinnamic acid gave a complex mixture of four different components. These were identified as the 1-cinnamyl glucuronate ester 13, the cinnamyl linked disaccharide 14, the glucuronate trichloroacetamide 15, and the glucuronyl alpha-fluoride 16. This paper rationalises the formation of each of these products, and reports our efforts in trying to optimise the formation of the alpha-fluoride 16.
