  Synthesis of highly pure oxyphytosterols and (oxy)phytosterol esters

  摘要：

  Several efficient synthetic routes giving readily access to (oxy)-sitosterol esters and (oxy)cholesterol esters derived respectively from oleic acid and from 9,10-dihydroxystearic acid were developed for the first time. This approach allowed that sufficient amounts of the latter were available in order to carry out further biological studies. (c) 2008 Elsevier Inc. All rights reserved.
