Synthetic Studies of 18-Membered Antitumor Macrolide, Tedanolide. 2. Stereoselective Synthesis of the C1-C7 Fragment via a Mismatched but Highly Efficient Sharpless Dihydroxylation

摘要

The C1-C7 fragment (4) of tedanolide (1) was synthesized starting from methyl (R)-3-hydroxy-2-methyl-propionate via a mismatched but highly efficient Sharpless dihydroxylation of the C1-C7 α,β-unsaturated ester (6) with AD-mix-α.
