合成路线1
该中间体在本合成路线中的序号：(II)Suzuki coupling between 4-methoxyphenylboronic acid (I) and 1-bromo-4-(trifluoromethoxy)benzene (II) gave the biphenyl derivative (III). Methyl ether cleavage in (III) by means of BBr3 provided the biphenyl alcohol (IV), which was condensed with (S)-benzyl glycidyl ether (V) under basic conditions, yielding the chiral glycerol diether (VI). Mitsunobu coupling of alcohol (VI) with the di-Boc-protected hydroxylamine (VII) using DEAD/PPh3 afforded carbamate (VIII). Subsequent catalytic hydrogenolysis of the benzyl ether of (VIII) gave alcohol (IX). Condensation of this alcohol (IX) with 5,5-dimethylhydantoin (X) under Mitsunobu conditions, followed by acidic cleavage of the Boc protecting groups, furnished the hydroxylamine derivative (XI). This was finally N-formylated by treatment with formic acetic anhydride.
