Lithiation of 4-benzyloxy-2-bromotoluene and subsequent quenching of the lithiated product affords 4-benzyloxytoluene-2-t which is oxidized directly to 4-benzyloxybenzaldehyde-2-t with ceric ammonium nitrate. Transformation of the aldehyde 6 by stand

gamma-L-Glutaminyl-[3,5-3H]4-hydroxybenzene was synthesized in order to study the kinetics of its hydroxylation by tyrosinase purified from Agaricus bisporus and to explore its role in the induction of the dormant state in the spores of this species.
