Relevant academic research and scientific papers

Synthetic studies of the 18-membered antitumor macrolide, tedanolide. 3. Stereocontrolled synthesis of the C1-C12 part via a synthesis of the C1-C7 fragment by a mismatched but efficient sharpless dihydroxylation and its coupling with the C8-C11 fragment

The C1-C12 part (4) of tedanolide (1) was synthesized starting from methyl (R)-3-hydroxy-2-methylpropionate (11a) via a coupling between the C1- C7 aldehyde (6) and the C8-C11 iodoalkene (7a). For a synthesis of 6, a mismatched but highly efficient Sharpless dihydroxylation of the α,β- unsaturated ester (15) with AD-mix-α was successfully applied. Compound 7a was synthesized using hydrozirconation to the alkyne (32).
