Studies directed towards the total synthesis of the antibiotic macrodiolide tartrolon: EPC synthesis of the protected seco acid
摘要:
An efficient synthesis of the protected seco acid 2 of the antibiotic macrodiolide tartrolon 1 is described. Key steps are a substrate controlled aldol-reaction, a Johnson-Claisen rearrangement, and a Horner-Wadsworth-Emmons olefination with subsequent Corey-Bakshi-Shibata (CBS) reduction.
