Iron-Catalyzed Arylalkoxycarbonylation of N-Aryl Acrylamides with Carbazates
摘要:
A novel arylalkoxycarbonylation of N-aryl acrylamides with carbazates leading to alkoxycarbonylated oxindoles has been developed. The reported reactions employ economical and environmentally benign FeCl2 center dot 4H(2)O as a catalyst and easily accessible and safe carbazates as alkoxycarbonyl radical precursors.
An iron-catalyzed alkoxycarbonylation/cyclization reaction of N-arylacrylamides with carbazates has been developed. This new alkene difunctionalization reaction provides an efficient and straightforward method to obtain various ester-containing oxindoles. (C) 2014 Elsevier Ltd. All rights reserved.
