New derivatives of thiamine were prepared by reacting succinic, glutaric or maleic anhydride with the hydroxyl group of thiamine. The resulting free carboxyl group was then activated using N, N, N′, N′-tetramethyl-O-(-N-succinimidyl)uronium tetrafluoroborate1 3 and conjugated to proteins. Alternatively, proteins were reacted with 2-iminothiolane and the resulting sulfhydryl groups were then added across the double bond of thiamine monomaleiate 2c prepared by the above method.
