A mild cyclodesulfurization of N-(2-hydroxyethyl)-N′-phenylthioureas to 2-phenylamino-2-oxazolines using TsCl/NaOH
摘要:
An efficient synthesis of 2-phenylamino-2-oxazolines 3 via cyclodesulfurization of N-(2-hydroxyethyl)-N ' -phenylthioureas 2 by a one-pot reaction using p-toluenesulfonyl chloride (TsCl) and NaOH in very good yields is described. (C) 2001 Elsevier Science Ltd. All rights reserved.
