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.
Synthesis of functionalized allylsilanes via palladium-catalyzed cross-coupling of 2-stannyl-3-silylpropene with organic halides.
摘要:
Allylsilanes bearing the various functionalities were prepared from the palladium-catalyzed cross-coupling reactions of 2-trimethylstannyl-3-trimethylsilylpropene with acid chlorides and with aryl halides.
