(±)-1-amino-2-cyclohexene-1,3-dicarboxylic acid (DHCGA),an unsaturated cyclic analogue of glutamic acid, was prepared from 3-carboxy-4-cyclohexenone by a Bucherer-Bergs reaction. Resolution was performed through coupling with L-leucine and separation of the resulting diastereoisomeric dipeptides. Spectral data, including optical rotation and circular dichroism of both enantiomers of DHCGA are reported
谷氨酸的不饱和环状类似物(±)-1-氨基-2-环己烯-1,3-二羧酸(DHCGA)由3-羧基-4-环己烯酮通过Bucherer-Bergs反应制备。通过与L-亮氨酸偶联并分离所得非对映异构二肽进行拆分。报道了DHCGA的两个对映异构体的光谱数据,包括旋光性和圆二色性。
