标题:Divergent Synthesis Of Lamellarin α 13-Sulfate,20-Sulfate,And 13,20-Disulfate
摘要:A Divergent Synthesis Of Three Sulfate Derivatives Of Lamellarin Alpha,Namely,Lamellarin Alpha 13-Sulfate (2),20-Sulfate (1),And 13,20-Disulfate (4) Has Been Achieved Via A Common Intermediate (6) In Which 13-Oh And 20-Oh Of The Lamellarin Core Are Differentially Protected By Mom And Benzyl Groups,Respectively. Compound (6) In Turn Was Prepared Using Sequential Suzuki-Miyaura Coupling Of 3,4-Dihydroxypyrrole Bistriflate (7) As A Key Reaction.
