Structural features of the Duocarmycins and Anthramycin were incorporated into 1,2,3,12a,12b-hexahydro-cyclopropa[1,2-d]benzo[f]pyrrolo[1,2-b]isoquinolin 5,7-dione. The synthesis of the cis and trans diastereomers was accomplished using a benzyne Diels-Alder reaction and an imine-anhydride cyclization as key steps.
Duocarmycins和Anthramycin的结构特征被并入1,2,3,12a,12b-六氢环丙烷[1,2- d ]苯并[ f ]吡咯并[1,2 - b ]异喹啉5,7-二酮中。顺式和反式非对映异构体的合成是使用苯并Diels-Alder反应和亚胺酐环化作为关键步骤完成的。
