A new two-step route to derivatives of homophenylalanine is presented. Cycloaddition of a cyclic nitrone glycine template with various styrene derivatives affords good yields of 5-substituted cycloadducts. One-step hydrogenolysis (three bonds) then affords the optically pure α-amino acids related to homophenylalanine.
提出了一种新的两步合成高苯丙氨酸衍生物的途径。环状硝酮甘氨酸模板与各种苯乙烯衍生物的环加成反应可提供良好的5取代环加合物收率。一步氢解(三键)可提供与高苯丙氨酸有关的光学纯α-氨基酸。
