合成路线图解说明:

Ethylenediamine (I) was selectively monoprotected as the N-Boc derivative (II) and then coupled with sulfonyl chloride (III), yielding sulfonamide (IV). After deprotection of the Boc group of (IV) with HCl in dioxan, the resulting amine (V) was condensed with hydroxyacid (VI) by means of BOP reagent to give amide (VII). Acid deprotection of the Boc group of (VII), followed by condensation with 2,6-dichlorobenzoyl chloride (IX), provided (X). Finally, the hydroxyl group of (X) was oxidized to the title ketone employing the Dess-Martin periodinane reagent in CH2Cl2.
