标题:A Total Synthesis Of Galbonolide B
摘要:[graphics]An Ester Enolate Rearrangement/silicon Mediated Fragmentation Cascade Was Used To Convert 7 And 8 Into The Alcohol 9. The Alcohol 9 Was Converted Into The Allylic Alcohol 12 And Then To The Ester 14. A Further Ester Enolate Rearrangement Furnished The Stereochemical Identity Of Galbonolide B 1. Base Mediated Macrocyclization Of The Acetate Ester 16 Followed By Base Mediated Alkylation And Acetal Deprotection Gave Galbonolide B 1.
