合成路线1

该中间体在本合成路线中的序号：(XI)

The intermediate biphenyl aldehyde (XI) is prepared by two related methods. 4-Bromo-3-methylbenzonitrile (I) is oxidized to aldehyde (II) via radical bromination with N-bromosuccinimide/benzoyl peroxide, followed by treatment with trimethylamine N-oxide. Suzuki coupling of aryl bromide (II) with the pinacol boronate (III) affords biphenyl (IV). After protection of the aldehyde moiety of (IV) as the corresponding ethylene ketal (V), its cyano group is reduced to aldehyde (VI) employing DIBAL in THF. Subsequent reduction of (VI) with NaBH4 leads to alcohol (VII), which is further converted into the benzyl bromide (VIII) by means of CBr4/PPh3. Bromide (VIII) is condensed with the spiro imidazolone (IX) in the presence of NaH, to produce (X). Then acidic hydrolysis of the ethylene ketal and SEM groups of (X) gives rise to the intermediate aldehyde (XI)

合成路线2

该中间体在本合成路线中的序号：(XI)

Alternatively, reduction of 4-bromo-3-formylbenzonitrile ethylene ketal (XII) by means of DIBAL leads to aldehyde (XIII), which is further reduced to alcohol (XIV) with NaBH4. After bromination of (XIV) with CBr4/PPh3, the resultant benzyl bromide (XV) is condensed with the spiro imidazolone (IX), yielding (XVI). Then, acidic ketal hydrolysis in (XVI) furnishes aldehyde (XVII). Suzuki coupling between aryl bromide (XVII) and boronic acid (XVIII) gives biphenyl (XIX). The SEM group of (XIX) is then removed under acidic conditions to provide (XI)
