Non-proteinogenic phenylalanine derivatives were efficiently prepared by Rh(I)-catalyzed [2+2+2] cycloaddition reactions between enantiopure and racemic propargylglycine amino acids, with different protective groups, and diynes. Diverse substituents, including tags such as dansyl or dabsyl, were introduced onto the aromatic ring of the amino acid derivatives by selecting the most appropriate diyne
通过Rh(I)催化的对映纯和具有不同保护基团的外消旋炔丙基甘氨酸氨基酸和二炔之间的Rh(I)催化的[2 + 2 + 2]环加成反应,可以有效地制备非蛋白质苯基丙氨酸衍生物。通过选择最合适的二炔反应伙伴,将包括标签如丹磺酰基或达布磺酰基在内的各种取代基引入到氨基酸衍生物的芳环上。
