Abstract

Biphenyltetrazoles are recognized privileged structures. Among them, the therapeutically important class of sartans displays antagonistic activity on AT1 receptors. We have developed a method for anchoring tetrazole derivatives via the heterocycle on a hydroxylated resin using zinc triflate. New Suzuki–Miyaura cross-coupling conditions are developed for the quantitative formation of the phenyl–phenyl bond. Our straightforward ...
