Highly stereoselective syntheses of alkenylsilanes and germanes utilizing cyclobutyl ketones
摘要:
(E)-alkenylsilanes 以高立体选择性合成,通过双相选择性加成二甲基芳香硅锂到转位-2-甲基环状单环三硫氰酸dehydes,以及配位酸促进行成的环状断裂反应所合成的环状乙醇二甲基交联产物。类似地,锌盐催化的环状断裂反应也能生产以高立体选择性合成(E)-1,5-二取代-1,5-二烯基硅烷和rades。该研究发表于1997年荷兰爱思 wer 出版社。

The triethylaluminum catalyzed ring opening reaction of 1-acetyl-2-[(trimethylsilyl)methyl]cyclobutanes gave (Z)-6-(trimethylsiloxy)-1,5-heptadienes stereoselectively. The starting materials were easily prepared by the 1,4-addition of (trimethylsilyl)methylmagnesium chloride to 1-cyclobutenyl ketones.
