Preparation of new tert-butyl substituted coumarins, thiocoumarins and dithiocoumarins

6-tert-Butyl-4-methyl- and 6,8-di-tert-butyl-4-methylcoumarin were prepared from tert-butylphenols and diketene via the corresponding aryl acetoacetates. 6-tert-Butyl-4-methyl-thiocoumarin (6) was obtained from 6-tert-butylthiophenol. Thionation with Lawesson's or Davy's reagent led to the related thion- and dithiocoumarins. The structures were proved by NMR spectroscopy and an X-ray structure analysis of 6.
