Asymmetric Synthesis of the C14–C26 Building Block of Eribulin Mesylate

Authors


Abstract

An alternative route for the synthesis of the C14–C26 building block of the anticancer drug eribulin mesylate is described. The key steps involved in the synthesis are a Julia–Kocienski olefination between aldehyde 4 and sulfone 5 and a tandem Sharpless asymmetric dihydroxylation/SN2 cyclisation reaction on mesyl compound 3.
