Total Synthesis of Mycalamide A. Further Synthetic Study of the Right Half
摘要:
The right half 5 of mycalamide A (1) was synthesized starting from (R)- or (S)-pantolactone via the Sharpless asymmetric dihydroxylation as the key step. The total synthesis of mycalamide A (1) was accomplished by coupling of the right and left halves.
The righthalf 5 of Mycalamide A (1) was synthesized via α,β-unsaturated ketone 11 which was prepared starting from (S)-malic acid or (R)- and (S)-pantolactones, stereoselectively.
