A novel atom-efficient, one-pot synthesis of sulfonylguanidines and sulfamoylguanidines
摘要:
An expedient one-pot procedure for the atom-efficient production of a variety of sulfonylguanidines and sulfamoylguanidines under mild conditions is described. The route constitutes an important alternative to current methods. (C) 2011 Elsevier Ltd. All rights reserved.
