A route to enantiomerically pure 5-(2′-hydroxyethyl)cyclopent-2-en-1-ol and its absolute configuration by Mosher esters
摘要:
The (+/-)-5-(2'-hydroxyethyl)cyclopent-2-en-1-ol 1 was prepared in a one-pot procedure, and was resolved using lipase AK and vinyl acetate with high ee. This provides a readily available chiral synthon for the synthesis of a wide variety of biologically interesting molecules. Further, the absolute configuration of diol 1 was confirmed directly by the Mosher ester method. (c) 2009 Elsevier Ltd. All rights reserved.
