  C5′-Alkyl Substitution Effects on Digitoxigenin α-l-Glycoside Cancer Cytotoxicity

  摘要：

  A highly regio- and stereoselective asymmetric synthesis of various CS'-alkyl side chains of rhamnosyl- and amicetosyl-digitoxigenin analogues has been established via palladium-catalyzed glycosylation with postglycosylated dihydroxylation or diimide reduction. The C5'-methyl group in both alpha-L-rhamnose and cc-L-amicetose digitoxin analogues displayed a steric directed apoptosis induction and tumor growth inhibition against nonsmall cell human lung cancer cells (NCI-H460). The antitumor activity is significantly reduced when the steric hindrance is increased at the C5'-stereocenter.

• N-Heterocyclic Carbene Catalyzed Dynamic Kinetic Resolution of Pyranones
  作者：Changgui Zhao、Fangyi Li、Jian Wang

  日期：2016.1.26

  The dynamic kinetic resolution of 6‐hydroxypyranones with enals or alkynals through an asymmetric redox esterification is catalyzed by a chiral N‐heterocyclic carbene. The resulting esters are obtained in good to high yields and with high levels of enantio‐ and diastereocontrol. The reaction products are further derivatized to obtain functionalized sugar derivatives and natural products.
