合成路线1
该中间体在本合成路线中的序号：(VII)Michael addition of ethyl acrylate (II) to the indenopyrrolocarbazole (I) provided (III). Lactam N-protection of (III) with dimethoxybenzhydrol yielded N-protected ethyl ester (IV), which was reduced with LiBH4 to give alcohol (V). Subsequent bromination of (V) with N-bromosuccinimide yielded (VI), which was first submitted to palladium-catalyzed carbonylation in methoxyethanol and then N-deprotected with trifluoroacetic acid and thioanisole to furnish (VII). Finally, reduction of ester (VII) with DIBAL furnished the diol intermediate (VIII).
