Chemistry of thioacylsilanes part 11. Cyclic and open chain α-silyl vinyl sulfides as precursors of thioannulated cyclopentenones and thiofunctionalized enones
摘要:
Cyclic and open chain a-silyl vinyl sulfides, obtained from thioacylsilanes, react with acid chlorides in the presence of Lewis acid to give thioannulated cyclopentenones and thiofunctionalized enones. The effect of the substituents at silicon on these reactions has been investigated. (C) 1997 Elsevier Science Ltd.

ω-Haloacylsilanes 1 were selectively transformed via thioacylsilanes into Z-silyl-enethiols 4 with solid sodium hydrogen carbonate or into 2-silylthiacycloalk-2-enes 5 of common to largeringsize with solid sodium hydroxide. Compounds 5 underwent protiodesilylation.
