Helicobacter pylori, a causative agent in gastric ulcers and gastric adenocarcinoma, for example. In our investigation of the practical synthesis of 1, we have developed an efficient method for stereoselectivesynthesis of trisubstitutedolefinsvia a Z-selective Wittigreaction. The olefination of readily available aliphatic α-acetal ketones with triphenylphosphonium salts in the presence of a potassium base
