method for the preparation of dicarba analogues of cystine as substituted benzene-, dihydrobenzene-, and tetrahydrobenzene-1,2-bis(alanine) derivatives is described. The partially saturated products resulted from Diels-Alder adduct formation with stereoselectively prepared (2R,7R)-2,7-diacetamido-4,5-bis (methylene)octane-1,8-dioic acid dimethyl ester. Aromatization of the dihydro adducts by manganese
摘要描述了一种用于制备作为取代苯-、二氢苯-和四氢苯-1,2-双(丙氨酸)衍生物的胱氨酸二卡巴类似物的通用方法。部分饱和的产物是由立体选择性制备的 (2R,7R)-2,7-diacetamido-4,5-双(亚甲基)辛烷-1,8-二酸二甲酯形成的 Diels-Alder 加合物形成的。二氢加合物通过二氧化锰的芳构化提供了母体苯-1,2-双(丙氨酸)衍生物。
