A cross metathesis approach to the synthesis of the C11–C23 fragment of (−)-16-normethyldictyostatin
摘要:
The synthesis of the C11-C23 fragment 2 of (-)-16-normethyldictyostatin has been achieved by cross metathesis between two olefinic fragments 4 and 5 followed by a reduction of the double bond at C16-C17. Both the olefinic fragments are easily synthesized in a diastereoselective manner from the common precursor alcohol 7. (c) 2006 Elsevier Ltd. All rights reserved.
