General procedure: To a solution of 12a-12i (1 equiv) in dried DCM was added 5-isoquinolinesulfonyl chloride HCl (1.2 equiv) and triethylamine (TEA) (1.2 equiv), and the resulting mixture was stirred for 2 h at RT. The resulting mixture was treated with saturated aq. NH4Cl (25 mL). The organic phase was extracted with DCM (3 x 25 mL),and the combined organic phases were dried over sodium sulfate, filtered and concentrated under vacuum. The residue was purifiedby silica gel column chromatography (CHCl3/MeOH 45:1, v/v) to afford 13a-13i.

General procedure: Table 3 is a parameter table. The starting material “parameter 1” was added into a flask at room temperature under N2, and then the “parameter 2” mL IPA and “parameter 3” were added thereinto. The starting material was dissolved at “parameter 4” C. The appearances of reaction solution were “parameter 5” and “parameter 7” in about “parameter 6” minutes, and then the solution was heated at 110~120C for “parameter 8” hours and concentrated in room temperature. The “parameter 9” mL MeOH was added and the resulting mixture was stirred for “parameter 10” minutes. To the solution, which is “parameter 1 1” in a ice-bath, NaBH4(s) “parameter 12” was added slowly under N 2 and stirred for “parameter 13” minutes. The solution, which is “parameter 14,” was added with “parameter 15” mL H2O and extracted with “parameter 16” mL CHC13. The organic layer was added with MgS04 for drying, stirred for “parameter 17” minutes, filtered, and concentrated to obtain “parameter 18”. The “parameter 20” was afforded after flash column chromatography (silica gel, “parameter 19”).
