Participants

Reaction Steps

To a solution of calcium hypochlorite (15.4 g, 72.4 mmol) in water:acetic acid (65:5) was added a solution of 8-trifluoromethoxychroman-4-one (4.2 g, 18.1 mmol; from step (iv) above) in acetonitrile (20 mL), whereafter the reaction mixture was stirred overnight. The mixture was diluted with water and extracted with ether (3 times) and EtOAc (once). The combined organic layer was washed with water, dried (Na2SO4) and evaporated, yielding 4.2 g (87%) of the sub-tide compound.
