Asymmetric syntheses of daedalin A and quercinol and their tyrosinase inhibitory activity
摘要:
Stereoselective syntheses of daedalin A and quercinol, an enantiomer of daedalin A, is described. The tyrosinase inhibitory activities of daedalin A and quercinol were examined. The activity of quercinol was weaker than that of daedalin A at high concentration. (C) 2009 Elsevier Ltd. All rights reserved.
