A new route to (Z)-beta-silylacryloylsilanes 10 and the improved conditions for the [3 + 2] annulation using 10 and alkyl methyl ketone enolates are reported. Also, details of investigations defining a reaction course of the [3 + 2] annulation using beta-phenylthio- and beta-trimethylsilyl-acryloylsilanes 1 (X = SPh, SiMe(3)) and alkyl methyl ketone enolates are described.
报道了一种新的制备(Z)-β-甲硅烷基丙烯酰基硅烷10的途径,以及使用10和烷基甲基酮烯醇盐改进[3 + 2]环化的条件。而且,描述了详细研究的定义,该研究定义了使用β-苯硫基和β-三甲基甲硅烷基-丙烯酰基硅烷1(X = SPh,SiMe(3))和烷基甲基酮烯酸酯的[3 + 2]环化反应的过程。
