Synthesis of α-methylenecyclopentanones via silicon directed nazarov reaction of α-trimethylsilymethyl substituted divinyl ketones.
摘要:
Reactions of alpha-trimethylsilylmethyl-substituted divinyl ketones with FeCl3 gave alpha-methylenecyclopentanones. Thienyl and N-methylpyrrolyl (alpha-trimethylsilylmethyl)vinyl ketones also underwent cyclization to afford the corresponding alpha-methylenecyclopentanones.
