N-Iodosuccinimide → trans-Racemic-2-(4-iodophenyl)cyclohexyl acetate

Participants

Reaction Steps

To a stirred solution of trans-racemic-2-phenylcyclohexyl acetate (5.60 g, 25.7 mmol) under nitrogen in TFA (50 ml) at 0° C. was added N-iodosuccinimide (5.77 g, 25.7 mmol) portionwise over 5 minutes. The mixture was allowed to warm and stir at room temperature for 3 hours. The mixture was concentrated under reduced pressure. The resultant oil was chromatographed using an 80 g silica gel cartridge eluted with 0-20% ethyl acetate in hexanes over 15 column volumes. The desired product fractions were combined and concentrated under reduced pressure to provide the desired product as a yellow oil. LC-MS: calculated for C14H17IO2 344.19 observed m/e: 345.33 (M+H)+ (Rt 2.60/4 min).
