Silver-catalyzed direct couplings of 2-substituted furans with cyclic 1,3-dicarbonyls
摘要:
Direct alkenylation of 2-substituted furans with cyclic 1;3-dicarbonyls by means of silver catalysis have been explored. Silver salts resulted more efficient than a variety of Lewis acids and p-TsOH. (c) 2007 Elsevier B.V. All rights reserved.
