Synthesis in ionic liquids only: access to α-oxo-γ-thio-esters via Mukaiyama coupling
摘要:
Ionic liquids are solvents general enough to conduct a multi-step process in organic synthesis. We show that both the preparation of starting materials (thioacetals and enoxysilane) as well as their coupling can be realized in such medium. (C) 2014 Elsevier Ltd. All rights reserved.
The reaction of dithioacetals with gallium(II) chloride followed by the acid treatment afforded sulfides in good yields.

Lewis acid-catalyzed reduction of dithioacetals by 1,4-cyclohexadiene
Dithioacetals were reduced by 1,4-cyclohexadiene in the presence of a catalytic amount of Lewis acid to afford the corresponding sulfides in good yields. (c) 2007 Elsevier Ltd. All rights reserved.
