摘要

Indoles with oxygen-bearing substituents such as a methoxy or (triisopropylsilyl) oxy group at all of the positions of the benzene moiety were synthesized by cyclization of tert-butyl methoxy (or (triisopropylsilyl) oxy)-2-((trimethylsilyl) ethynyl) phenyl) carbamates with potassium tert-butoxide in tert-butyl alcohol. The (ethynylphenyl) carbamates were synthesized by the palladium-catalyzed reaction of (trimethylsilyl) acetylene and the ...
