Facile and Efficient Sulfenylation Method Using Quinone Mono-O,S-Acetals under Mild Conditions
摘要:
A novel sulfenylation method induced by aromatization of quinone mono-O,S-acetals is described. These sulfenylation reagents readily react with silyl enolethers or electron rich aromatic compounds to give sulfenylation products under mild conditions. In particular, O,S-acetal 2j, which possesses a pentafluorophenylthio function, is the most effective reagent from the standpoint of the adaptability for various substrates.

A facile sulfenylation of various aromatic nuclei was achieved by use of the novel sulfenylation reagent, the quinone mono O,S-acetal bearing a pentafluorophenylthio group. This reagent functions below 0 degreesC in the presence of a catalytic amount of TMSOTf. (C) 2001 Elsevier Science Ltd. All rights reserved.
