Various optically pure 3-substituted dihydroorotic acids (9, 12) were synthesized by the N-alkylation and Mitsunobu reaction of optically active benzyl or tert-butyl dihydroorotate (6, 10), followed by deprotection of the ester group.Moreover, optically pure 1-methyl (16, 17) and 1-ethyl (19) dihydroorotic acids were obtained by an optical resolution method.
通过对具有光学活性的二氢乳清酸苄酯或叔丁酯(6、10)进行 N-烷基化和三丁反应,然后对酯基进行脱保护,合成了各种光学纯度的 3-取代二氢乳清酸(9、12)。
