First synthesis of the antifungal and antibacterial agent cladobotryal
Abstract
The antifungal and antibacterial agent cladobotryal (1) was synthesized by a convergent route from lactone 5 and aldehyde 12, a key step in the elaboration of the pyridinone ring being conversion of a t-BuOC(O) group on nitrogen into an i-Pr3SiOC(O) group.
