An expedient radical based approach to difluorophosphonate analogues of thionucleosides
摘要:
An expedient approach to difluorophosphonate analogues of thionucleosides of general structure 1 is described; the key step is a radical xanthate transfer chain reaction on diethyl 1,1-difluoro-3-butenylphosphonate. (C) 1998 Elsevier Science Ltd. All rights reserved.
