A round-bottom flask was charged with compound 3 (1.75 g, 5.27 mmol), LiCl (1.17 g, 26.3 mmol), DMSO (100 mL) and H2O (378ul)
2. 催化量的Et3N (20 mL, 142 mmol) and a catalyticamount of DMAP were added the solution of compound 1 (4.549 g, 46.4mmol) in CH2Cl2 (120 mL) at 0oC
3. 气体保护To a stirred -78oCsolution of trimethylsilyacetylene (4.44 g, 45.5 mmol) in THF (10 mL) under Argon wasadded dropwise n-butylithium (1.6 M in hexane, 28.25 mL).
4. 通入气体An ozone-enriched steam of oxygen was bubbled througha cold (-78oC) solution of compound 9 (128 mg, 1.409 mmol) in CH2Cl2 (5 mL) untilit turned light blue. The solution was purged with argon at -78oCfor 10 min to remove the excess O3.
5. 通过双针头导管加料The mixture was added to a solution of compound 2 (3.00 g, 12.8 mmol) in THF (48mL) via cannula over a period of 30 min. A solution of compound 29 (100 mg, 0.19 mmol, 1.0 equiv) in dry DMSO (1.5 mL) wascannulated under Argon to a vigorously stirred mixture of powered potassiumsuperoxide (62 mg, 0.87 mmol, 4.5 equiv) and 18-crown-6-ether (23 mg, 0.087mmol, 0.45 equiv) in dry DMSO (0.5 mL).
6. 通过注射器加料To a stirred solution of compound 15 (8.61 g, 21.2 mmol)was added a solution ofp-toluenesulfonicacid (6.0 g) in CH2Cl2via syringe over 5 min.
二、反应过程常用表述
1. 反应检测After 1 h, TLC analysis (CH2Cl2/ hexane 3:1) showed the complete consumption of compound 15.
2. 放置过夜The mixture was left standing overnight.
3. 甲苯/乙醇带水Compound A(1.97 g, 6.63 mmol) was coevaporatedwith toluene five times to remove the water. The residue was subjected to toluene azeotrope to givethe corresponding acid chloride as brown oil. The aqueous portion was concentrated underreduced pressure followed by azeotropic removal of water with absolute EtOH
4. 氢化反应A mixture of compound 1 (190 g, 0.88mmol) and Raney Ni (20 g) inethanol (1500 mL) and ethyl acetate (500 mL) was stirred under 1 atm at room temperaturefor an hour.
5. 分水器A mixture of TsOH.H2O (56.91 g, 0.3 mol) and toluene (400 mL) washeated to reflux to remove water by Dean-Stark trap.

三、后处理过程常用表述
1. 过滤The mixture was filtered through a Celite pad, and thefiltrate was concentrated to give the crude product.
2. 淬火The reaction mixture was quenched by the addition of thesaturated aqueous NH4Cl.
3. 磨碎The residue was triturated with ether and filtered to afforda white solid.
4. 在两相中分开The residue was partitioned between ethyl acetate (100mL) and HCl (1 M aq., 50mL). The organic layer was washed with water, dried (MgSO4) andevaporated to dryness. Ethyl acetate (100 mL) and HCl (1 M aq., 50 mL) were added to the residue,and the layers were separated.
5. 静止固化The crude product was purified by prep-HPLC to givecompound 4 as colorless thick oil,which was solidified on standing.
6. 在冻干机冻干The white solid was re-crystallized from water, driedby hyophilization to give a white solid.
7. 纯化过柱The crude product was chromatographed on silica gel(CH2Cl2 / MeOH 20:1→10:1→5:1) to give the compound 8 (0.282 g,51%) as a white solid. The crude product was purified by column chromatographyon silica gel eluted with (CH2Cl2 / MeOH 20:1→10:1→5:1)to give the compound 8 (0.282 g,51%) as a white solid.
