00 μl (1.41 mmol) was added dropwise over 6 minutes and stirred for 12 minutes. The 7,7-dimethyl-1,5-dihydroxy-12- (2-acetylthioethyl) bicyclo [8.3.0] tridec-10-ene-3,8- obtained in Example 15 was added to the cloudy reaction solution. A solution of 0.0492 g (0.148 mmol) of diyne in 1.5 ml of anhydrous dichloromethane was added dropwise over 15 minutes.
At this time, 7,7-dimethyl-1,5-dihydroxy-1
2- (2-acetylthioethyl) -bicyclo [8.3.
0] A container containing a dichloromethane solution of tridec-10-ene-3,8-diyne was washed with 0.5 ml of anhydrous dichloromethane. Stirring was continued at −75 ° C. for 60 minutes, whereupon 310 μl (2.22 mmol) of triethylamine was added.
Was added dropwise over 1 minute. Heat to -60 ° C for 18 minutes, 0
After stirring at 1 ° C. for 1 minute, the reaction was stopped by adding water.
The mixture was extracted three times with 10 ml of dichloromethane, and the organic layer was washed with 8 ml of saturated saline, dried over magnesium sulfate, filtered and the solvent was removed. The removal of the solvent was carried out promptly at room temperature, and at this time, the solvent was kept small enough. The residue was immediately purified by column chromatography using 4 g of silica gel and hexane: ethyl acetate = 4.4: 1, and the solvent was quickly removed at room temperature or lower to obtain the desired product.
