Abstract
Here, as part of our explorative work on the synthetic use of DIH, [¹0] we would like to report an efficient preparation of the chroman skeleton from 3-aryl-1-propanols and related reactions with DIH under irradiation with a tungsten lamp. Table [¹] shows the results of the reaction of 3-phenyl-1-propanol with DIH under irradiation with a tungsten lamp (300 W) in ethyl acetate and 1,2-dichloroethane (DCE). When the reaction was carried out in ethyl acetate, ...
