Aza-Michael Access to Fluoroalkylidene Analogues of Biomolecules
摘要:
The synthesis of fluoroaminosulfones derived from piperidine and nucleic bases followed by the study of their chemical behavior in the modified Julia reaction are described. The resulting aminosulfones open a straightforward access to a series of new fluorinated biomolecules including a potent DPP-II inhibitor and acyclonucleoside analogues as potential enzyme inhibitors.
