Synthesis andin VitroEvaluation of N-[[4-[2-(Carboxyl)-1-Cycloalken-1-yl]Phenyl]Methyl]Imidazoles as Nonpeptide Angiotensin II Receptor Antagonists

Total Synthesis of (+/-)-Cylindricines A and B

Cylindricine A (1) and cylindricine B (2) have been synthesized in 11 steps and 19% overall yield. The key reaction involves the addition of an organocopper species to a bicyclic vinylogous amide, which provides complete stereocontrol over the installation of the hexyl side chain.
