β-Nitroacrylates as key starting materials for the one-pot synthesis of densely functionalized penta-substituted anilines
摘要:
The reaction of ylidene malononitriles with beta-nitroacrylates, in Et3N/MeCN, affords the one-pot synthesis of a new class of penta-substituted, densely functionalized anilines in satisfactory to good overall yields. The method represents a very important improvement of the recent strategy for the preparation of anilines from conjugated nitroalkenes. (C) 2012 Elsevier Ltd. All rights reserved.
