Copper carbenoid mediated N-alkylation of imidazoles and its use in a novel synthesis of bifonazole
摘要:
1H-Imidazoles are readily N-alkylated by a Cu(acac)(2) mediated reaction with alpha-diazocarbonyl compounds or with diazoalkanes generated in situ from the corresponding p-toluensulfonyl hydrazones. The antifungal agent bifonazole was prepared by the latter method. (C) 2004 Elsevier Ltd. All rights reserved.
