摘要：

A general fluorous thiol quenching method is introduced. Excess alpha-bromoketones or benzyl bromides in parallel N-alkylation reactions are quenched with a fluorous thiol (C6F13CH2CH2SH). The resulting fluorous derivatives can be separated from the reaction mixture by a solid phase extraction on fluorous silica gel. (C) 2002 Elsevier Science Ltd. All rights reserved.
