Some reactions such as catalytic hydrogenation, Diels-Alder reaction, cyclopropanation, dihydroxylation, and Michael addition of a novel 3,4-didehydropyroglutamate derivative, in which the carboxylic group is protected as an ABO ester, are examined and found to take place in a stereospecific manner giving 3- and/or 4-substituted pyroglutamate derivatives without loss of enantiomeric purity at the alpha-position
考察了一些反应,例如催化氢化,狄尔斯-阿尔德反应,环丙烷化,二羟基化和新型3,4-二氢脱氢谷氨酸衍生物的迈克尔加成反应,其中羧基作为ABO酯被保护,立体定向的方式得到3-和/或4-取代的焦谷氨酸衍生物,而在α-位没有损失对映体纯度。
