Organolithium mediated synthesis of prenylchalcones as potential inhibitors of chemoresistance
摘要:
A number of substituted chalcones have been prepared by a novel LiHMDS-mediated aldol condensation, the first method consistent with the use of alkali-labile protecting groups such as tert-butyldiphenylsilyl or tert-butyldimethylsilyl. Chalcone substitution by prenylation increases their binding affinity to P-glycoprotein responsible for cancer cells chemoresistance. (C) 1999 Elsevier Science Ltd. All rights reserved.
