实验过程

1,1,1-Tris(acetyloxy)-1,1-dihydro-1,2-benziodoxol-3-(1H)-one (44 mg, 0.104 mmol) was added to a solution of the alcohol 14 (42 mg, 0.087 mmol) in CH2Cl2 (2 mL) at 23° C. After stirring for 16 h the reaction mixture with CH2Cl2 and filtered. The filtrate was concentrated in vacuo and purification of the residue by flash column chromatography (silica gel, 1:1 hex/EtOAc) gave 41 mg (98%) of the ketone 16.
