英文摘要: Selective glycosylation of the 3-OH of 5,4'-di-O-acetyl-kaempferol was achieved with glycosyl orthoalkynylbenzoates as donors under the catalysis of Ph(3)PALINTf(2), and subsequent glycosylation of the remaining 7-OH with glycosyl trifluoroacetimidates under the catalysis of BF3.OEt2, after global deprotection, afforded the kaempferol 3,7-O-bisglycosides conveniently.
