合成路线1

Tetrahydrobenzothiophene-4-one (I) was treated with hydroxylamine to afford oxime (IIa-b) as a mixture of syn and anti isomers, which were condensed with tosyl chloride yielding the oxime O-tosylate (IIIa-b). Beckmann rearrangement of (IIIa-b) in the presence of KOAc gave rise to lactam (IV), and subsequent reduction with borane provided thienoazepine (V). Condensation of (V) with 2-chloro-4-nitrobenzoyl chloride (VI) gave amide (VII). A 7-oxo group was introduced by oxidation of (VII) with KMnO4 in acetone-water. The resulting ketone (VIII) was treated with Bredereck’s reagent to afford the dimethylaminomethylene ketone (IX). Cyclization of (IX) with hydrazine produced the tricyclic compound (X). The nitro group of (X) was then reduced to amine (XI) using stannous chloride. Coupling of (XI) with 2-biphenylcarbonyl chloride (XII) furnished the diacylated derivative (XIII). Finally, selective monodeacylation of(XIII) with NaOH yielded the title compound.
