PIDA-mediated synthesis of oxazoles through oxidative cycloisomerization of propargylamides
摘要:
PIDA [phenyliodine(III) diacetate] in AcOH or AcOH-HFIP (hexafluoroisopropanol) efficiently promotes the formation of 2,5-disubstituted oxazoles via the oxidative cycloisomerization of propargylamide derivatives. (C) 2010 Elsevier Ltd. All rights reserved.
