Stereodefined dinucleoside (3′,5′)-propionamidophosphonates and β-cyanoethylphosphonates and their incorporation into modified oligonucleotides
摘要:
Base-catalyzed stereospecific anti-Markovnikov addition of dinucleoside (3',5')-H-phosphonates to the activated alkenes acrylamide and acrylonitrile resulting in the synthesis of P-chiral diastereomerically pure dinucleoside (3',5')-alkylphosphonates is reported. (C) 2009 Published by Elsevier Ltd.
