Chemoenzymatic synthesis of deoxy analogues of the DNA topoisomerase II inhibitor eleutherin and the 3C-protease inhibitor thysanone
摘要:
The asymmetric synthesis of (-)-9-demethoxyeleutherin 6, (+)-9-demethoxyeleutherin 7 and (+)-7,9-deoxythysanone 8 has been achieved using a microwave assisted kinetic resolution of racemic alcohol 11 with Novozyme 435 (R) as the key step. (C) 2008 Elsevier Ltd. All rights reserved.
