Construction of Optically Active Spiroketal by Direct Aldol Reaction
摘要:
Novel preparation of symmetric spiroketal was developed by the use of direct aldol reaction of alpha-hydroxyacetophenone catalyzed by chiral dinuclear zinc catalyst. The spiroketal was obtained in excellent enantiomeric excess.
