Synthesis of 3-alkyloxazolidin-2,4-diones using 2-chloroacetamides, carbon dioxide and 1,8-diazabicyclo[5.4.0]undecene (DBU)
摘要:
Diazabicyclo[5.4.0]undecene (DBU) reacts with carbon dioxide and N-substituted-2-chloroacetoamides in a very simple one-step procedure, to give the corresponding 3-substituted oxazolidin-2,4-diones in excellent yields. (C) 2009 Elsevier Ltd. All rights reserved.
