Concise synthesis of taxol a-ring components: Remote diastereoselective additions of alkenyl lithiums to aldehydes
摘要:
The acid chloride 6 provides access to 7 (R,S and S,S) which upon bromine-lithium exchange undergoes remarkably highly diastereoselective additions to aldehydes; 7 is also readily elaborated into the acetal 10. Copyright (C) 1996 Elsevier Science Ltd
