3-Phosphono-2-(N-cyanoimino)thiazolidine derivatives, new phosphorylating agents for alcohols
摘要:
We have developed new phosphorylating agents, 3-phosphono-2-(N-cyanoimino)-thiazolidine derivatives (3-phosphono-NCTs), which were readily synthesized by phosphorylation of NCT, and transformed primary and secondary alcohols into phosphates in good yield. The transfer of three kinds of dialkylphosphono groups [(PhO)(2)P(O)-, (EtO)(2)P(O)-, (Cl3CCH2O)(2)P(O)-] proceeded in excellent yields. Selective phosphorylation of various alcohols was also accomplished. (C) 2002 Elsevier Science Ltd. All rights reserved.
