合成路线1
该中间体在本合成路线中的序号:(I)The hetero Diels-Alder condensation of quinolinedione (I) with the azabutadiene (II) in the presence of ZnBr2 produced regioselectively the pyridoquinoline (III). Benzylic bromination of (III) using N-bromosuccinimide then gave bromomethyl derivative (IV). Subsequent treatment of (IV) with NaOAc in DMF, followed by hydrolysis of the resulting acetate (V), afforded 3-(hydroxymethyl)pyridoquinoline (VI). This was finally treated with isopropyl isocyanate in the presence of Et3N and dibutyltin diacetate to yield the target carbamate.
