Yield:14371-10-9 91%

Reaction Conditions:

with 1-hydroxy-1H-1,2,3-benziodoxathiole 1,3,3-trioxide;Oxone;cetyltrimethylammonim bromide in water at 20; for 2 h;Green chemistry;chemoselective reaction;

Steps:

IBS-catalysed alcohol oxidation in CTAB micelle; general procedure

General procedure: The alcohol (2 mmol) was added to a solution of IBS (0.02 mmol, 0.01 eq), oxone (2.2 mmol, 1.1 equiv.) and 3 wt% CTAB solution (5 mL). The mixture was stirred at room temperature. The reaction was monitored by TLC. After completion, the solution was extracted with CH2Cl2 (3 × 10 mL). The combined organic phase was then filtered through a pad of silica gel and evaporated under vacuum to afford the desired product.
