The total synthesis of swinholide A. Part 1 : A stereocontrolled synthesis of a C19-C32 segment

The C19-C32 segment 10 of swinholide A was prepared in 15 steps (8% yield, 82% ds) from (±)-16. Key steps include (i) the Sharpless epoxidation, 16 → 17, (ii) the acetal allylation, 15 → 23, (iii) the anti aldol addition, 13 + 14 → 1
