Electroreductive acylation of aromatic imines with acylimidazoles
摘要:
The intermolecular reductive coupling of aromatic imines with acylimidazoles was effected by electroreduction in the presence of chlorotrimethylsilane and gave a-amino-a-aryl ketones. This method was also effective for the synthesis of alpha-amino-alpha-aryl esters using methoxycarbonylimidazole as an electrophile. (c) 2007 Elsevier Ltd. All rights reserved.
Electroreduction of aromatic imines in the presence of electrophiles gave the corresponding inter- and intramolecular coupling products when the reaction was carried out with the use of chlorotrimethylsilane (CTMS) as the trapping agent of an anion intermediate.
