A General and Enantioselective Approach to Pentoses: A Rapid Synthesis of PSI-6130, the Nucleoside Core of Sofosbuvir
摘要:
An efficient route towards biologically relevant pentose derivatives is described. The de novo synthetic strategy features an enantioselective alpha-oxidation reaction enabled by a chiral amine in conjunction with copper(II) catalysis. A subsequent Mukaiyama aldol coupling allows for the incorporation of a wide array of modular two-carbon fragments. Lactone intermediates accessed via this route provide a useful platform for elaboration, as demonstrated by the preparation of a variety of C-nucleosides and fluorinated pentoses. Finally, this work has facilitated expedient syntheses of pharmaceutically active compounds currently in clinical use.
Novel rapamycin analogs and uses thereof are disclosed herein. The rapamycin analogs of the present disclosure show increased mTORC1 specificity and lowered mTORC2 specificity relative to rapamycin.
Compounds are provided to modulate the C5a receptor. The compounds have the following Formula (I):
including stereoisomers and pharmaceutically acceptable salts thereof, wherein R
