摘要:
Two routes for the synthesis of the marine natural product trans-laurediol 6 are described. In the first approach 6 is obtained in ten steps and 21% overall yield from monoacetone D-glucose. The second route provides the target in eleven steps and 13% yield from D-mannose. Both routes are more efficient, both in terms of number of steps and overall yield, than previously reported syntheses. (C) 2003 Elsevier Science Ltd. All rights reserved.
