The racemic and both chiral forms of cyclopropans-1,2-d 2 and cyclopropane-1- 13 C-1,2,3-d 3 have been prepared efficiently through sequences based on trans-1,2-bis(methoxycarbonyl)cyclopropanes. These diesters have been prepared in racemic form with 1,2-d 2 labeling and with 3- 13 C-1,2,3-d 3 labeling. The labeled diesters have been resolved to provide both chiral forms, and the racemic or resolved
环丙烷-1,2-d 2 和环丙烷-1-13 C-1,2,3-d 3 的外消旋和手性形式已通过基于反式-1,2-双(甲氧基羰基)环丙烷的序列有效制备. 这些二酯已制备成外消旋形式,带有 1,2-d 2 标记和 3- 13 C-1,2,3-d 3 标记。标记的二酯已被拆分以提供两种手性形式,并且外消旋或拆分的二酯已通过涉及还原和脱羰的两步序列转化为相应的特定标记的外消旋或手性环丙烷
