Chemoselective Coupling Reactions of 5,7-Dimethoxyphthalide with the Remotely Functionalized Alkyl Iodides: Facile Racemic Synthesis of Helicobacter pylori Antibiotics
摘要:
Highly chemoselective coupling reactions of 5,7-dimethoxyphthalide carbanion with the remotely functionalized long chain alkyl iodides have been demonstrated to accomplish the concise and efficient synthesis of Helicobacter pylori antibiotics, the CJ-molecules, and sporotricale methyl ether.
