合成路线1
该中间体在本合成路线中的序号:(VIII)The cyclization of the diazo azetidinone (I) by means of a Rhodium catalyst in dichloromethane gives the -methyl-2-oxocarbapenam derivative (II), which is treated with methanesulfonic anhydride and TEA in dichloromethane yielding the enol triflate (II). The silylation of the OH group of (III) with triethylsilyl triflate and TEA affords the silyl ether (IV), which is condensed with the fluorenone boronic acid (V) by means of KOH and a Pd catalyst giving the adduct (VI) (1). The mesylation of (VI) with MsCl and TEA in dichloromethane, followed by reaction with NaI in acetone yields the iodomethyl compound (VII), which is condensed with 2-(4-aza-1-azoniabicyclo[2.2.2]octan-1-yl)acetamide triflate (VIII) by means of silver triflate in THF/acetonitrile to afford the protected intermediate (IX). Finally, this compound is deprotected first with HCl in THF/water and then by hydrogenation with H2 over Rh/C. The intermediate 2-(4-aza-1-azoniabicyclo[2.2.2]octan-1-yl)acetamide triflate (VIII) has been obtained as follows: The condensation of 1,4-diazabicyclo[2.2.2]octane (X) with 2-bromoacetamide (XI) in acetonitrile gives 2-(4-aza-1-azoniabicyclo[2.2.2]octan-1-yl)acetamide bromide (XII), which is then treated with silver triflate in acetonitrile/methanol to yield (VIII).

该中间体在本合成路线中的序号:(XLV)Coupling of carbapenem (XLII) with sultam (VIIIb) under Mitsunobu conditions gave adduct (XLVII), which was desylilated to yield alcohol (XLVIII). Formation of the corresponding triflate, followed by condensation with bicyclic compound (XLV) provided (II), which was converted to (L) upon treatment with HCl and NaCl. The p-nitrobenzyl ester of (L) was finally deprotected by hydrogenation over Pd/C to provide the title carboxylic acid. A further procedure to obtain the target compound is to repeat the described synthesis but using carbapenem (XXXVII), instead of carbapenem (XLII).

Alternatively, 4-methylnaphthalen-1-ylsulfonyl chloride (II) can be condensed with diethylamine giving the corresponding sulfonamide (XIII), which is nitrated with nitric and sulfuric acids yielding the 8-nitro derivative (XIV). Finally, this compound is cyclized to the previously reported naphthosultam (VI) by hydrogenation with H2 or potassium formate over Pd/C.
