Total synthesis of (−)-dactylyne and (−)-isodactylyne
摘要:
The first total synthesis of (-)-dactylyne (1) and (-)-isodactylyne (2), which are isolated from sea hare, is described via intermediates 3-15 and 17-18. Critical steps in the synthesis include a stereoselective construction as well as an intramolecular ring closure of 12, and the effective double elongation reactions (15 --> 17 and 17 --> 18).
