Reaction of Dimethyl Sulphoxide and Acetic Anhydride with 3-Substituted 4-Hydroxycoumarins

The DMSO-Ac2O reagent reacts with 4-hydroxy-3-phenylcoumarin to give 3-(2-hydroxyphenyl)-2-phenyl-1-thiomethylpropan-3-one (1a) and 6H,11H-benzopyranobenzopyran-11-one (3).A similar reaction of 3-allyl-4-hydroxycoumarin gives 2-allyl-3-(2-hydroxyphenyl)-1-thiomethylpropan-3-one (1b).However, the same reagent, when modified by prior heating, reacts with 6H,7H-7-(4-hydroxy-3-coumaranyl)benzopyranobenzopyran-6-one (7a) to give dicoumarol, 7-thiomethyl-6H,7H-benzopyranobenzopyran-6-one (8) and 4-hydroxy-3-methylthiomethoxy-2H-benzopyran-2-one (10).
