General procedure: At 0 ¡ãC and with stirring to the solution of 865 mg (5.0 mmol) of isoquinoline-3-carboxylic acid in 10 ml of anhydrous THF 675 mg (5.0 mmol) of HOBt was added to form reaction mixture A. The solution of 5.5 mmol of l-amino acid benzylester in 5 ml of anhydrous THF was adjusted pH 9 with triethylamine and stirred for 30 min to form mixture B. At 0 ¡ãC the mixtures A and B were mixed and then 1339 mg (6.5 mmol) of DCC was added. The reaction mixture was stirred at 0 ¡ãC for 2 h, at room temperature for12 h and TLC (ethyl acetate/petroleum ether, 1:2) indicated the complete disappearance of isoquinoline-3-carboxylic acid. The formed precipitates of DCU were removed by filtration and the filtrate was evaporated under vacumm. The residue was dissolved in 50 ml of ethyl acetate and the formed solution was washed successively with saturated aqueous solution of NaHCO3 (30 ml .x. 3), 5percent aqueous solution of KHSO4 (30 ml .x. 3) and saturated aqueous solution of NaCl (30 ml .x. 3) and dried over anhydrous Na2SO4. After filtration the filtrate was evaporated under vacumm and the residure was purified on silica gel chromatography (CHCl3:MeOH, 20:1) to give the title compounds.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.6624-49-3,Isoquinoline-3-carboxylic acid,as a common compound, the synthetic route is as follows.

General procedure: To the resin 13 (560 mg) in DMF (2.5 mL) were added a solutionof the appropriate Fmoc-protected amino acid (see Tables 1?3)(0.3 M), PyBOP (0.3 M) and HOBt (0.3 M) in dry DMF (4.2 mL). Thesuspensions were stirred for 3 min and then DIPEA (0.6 M) wasadded. The suspensions were stirred for 3 h under an argon atmosphereat rt. The resins were washed successively with DCM(150 mL), MeOH (120 mL), DCM (75 mL) and dried overnight undervacuum to give resins 14, each bearing an appropriate Fmoc-protectedamino acid. To the resins 14 (161 mg, 0.13 mmol) wereadded a solution of piperidine (20percent, v/v) in DCM (2.1 mL) and themixtures were stirred for 1 h at rt. After filtration, the resins werewashed successively with DCM (50 mL), MeOH (45 mL), DCM(25 mL) and dried under vacuum to give resins 15. Portions(65 mg) of resins 15 were placed in reactor wells (12 mL) of anautomated synthesizer reaction block (40-well format) (AdvancedChemTech). To each well was added a solution of appropriate carboxylicacid (see Tables 1?3) (0.3 M), PyBOP (0.3 M) and HOBt 6-Cl(0.3 M) and DIPEA (0.6 M) in dry DMF (2 mL). The suspensionswere vortexed at 300 rpm over a period of 5 h under an argonatmosphere. The wells were then filtered to remove the reactivesolution from the resins 16 and washed successively with THF,DCM, MeOH and DCM., 6624-49-3

6624-49-3, A solution of 2 (519.0 mg, 3.0 mmol) and mono-N-Boc-protected TREN (3) (246.0 mg, 1.0 mmol) in DMF (50 mL) was prepared at room temperature under nitrogen. While stirring, DMTMM (4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholiniumchloride) (830.1 mg, 3 mmol) and NMM (N-methylmorpholine) were added (dropwise 2-3 ml) to get a pH of about 9. Then solution was diluted with methanol (10 ml) and allowed to stir at room temperature. After 12 h, the solvent was removed in vacuo and the residue was dissolved in ethyl acetate. After removal of solvent the crude product was purified by column chromatography using silica gel and CH2Cl2:MeOH (20:1). The product 4 (338.6 mg, 61%) was obtained as a white solid.

General procedure: The ligand (1 eq) and sodium methoxide (1.1 eq) were dissolved in dry methanol (10mL) and after stirring at room temperature for 15min, [RhCp*(mu-Cl)Cl]2 (0.9 eq) was added. The mixture was stirred under argon atmosphere and at room temperature for 24h. The solvent was subsequently removed under reduced pressure; the obtained residue was taken up in CH2Cl2 and filtered to remove insoluble reaction by-products. The filtrate was concentrated to a volume of 2mL under reduced pressure. Precipitation with n-hexane afforded the desired product in moderate to good yields (53?64percent)., 6624-49-3

General procedure: Mixtures of 4-(di-tert-butoxycarbonylamino)-6-amino-2-methylquinoline (100mg, 0.27mmol), the respective carboxylic acid (0.53mmol, 2equiv), 2-(7-aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU; 190mg, 0.500mmol, 2.0equiv) and di-iso-propylethylamine (0.5mL, 2.9mmol, 10equiv) in DMF (5mL) were stirred at room temperature for 16h. The mixtures were poured into 50mL of 5percent aq Na2CO3 and extracted with EtOAc (3¡Á50mL). The combined organic layers were washed with 5percent aq Na2CO3 (1¡Á50mL), brine (1¡Á50mL), dried (MgSO4), and evaporated. The residual materials were co-evaporated with diethyl ether and treated without further purification with 1:1 TFA/DCM (5mL) for 30min?2h. Removal of solvents gave crude materials as solids or oils that were triturated with diethyl ether and recrystallized from CH3CN/MeOH) to yield the final product as a TFA salt or purified using prep TLC (80:18:2 CHCl3/MeOH/aq CH3NH2) to provide the free base. Some of the free bases were further reacted with a slight excess of p-toluenesulfonic acid in diethyl ether to provide the corresponding p-TsOH salts.
