Reaction of a variety of 1,2-epoxyalkanes with 2.5 equiv. of bulky metal amide—lithium 2,2,6,6-tetramethylpiperidide—affords the corresponding aldehydes exclusively in high yields; this is the first example of base-promoted isomerization of monosubstituted epoxides to aldehydes.
各种1,2-环氧烷与2.5当量的反应。笨重的金属酰胺(2,2,6,6-四甲基哌啶锂)仅以高收率提供相应的醛;这是单取代的环氧化物被碱促进为醛的异构化的第一个例子。
