Abstract
The Rosenmund catalyst (Pd/BaSO4) was found to efficiently catalyze debenzylation of N-benzyltetrazole derivatives with ammonium formate by catalytic transfer hydrogenation under mild conditions. The protocol has been applied to functionalized substrates to provide various angiotensin II receptor blockers in excellent yields.
