Four-Component Benzyne Coupling Reactions: A Concise Total Synthesis of Dehydroaltenuene B
摘要:
A four-component coupling reaction of 3,5-dimethoxybenzyne with 2-methyl-2-cyclohexenylmagnesium chloride, carbon dioxide, and iodine was utilized as a key step in the first total synthesis of dehydroaltenuene B.
