Allylsilanes preapared from α-aminoacids react with acyl chlorides in the presence of TiCl4 to give unsaturated amino ketones, easily transformed into pyrrolidine derivatives, whereas addition to aldehydes gave 2,6-disubstituted tetrahydropyridines.
在TiCl 4的存在下,由α-氨基酸制成的烯丙基硅烷与酰氯反应,生成不饱和氨基酮,易于转化为吡咯烷衍生物,而除醛外,生成2,6-二取代的四氢吡啶。
