4-thio substituted coumarin derivatives and coumarin dimers are provided, as well as processes for their preparation. A synthetic process for the preparation of 4-thio substituted coumarin derivatives is provided using mild reaction conditions, which maintains a high substituent tolerance and is appropriate for use in solid phase syntheses for producing a library of 4-thio substituted coumarin derivatives for biological screening.
The direct sulfanylation of 4-hydroxycoumarins with thiols via C–OH bond activation in water under mild conditions is described, which afforded the corresponding 4-sulfanylcoumarins in good yields.

Diversified 4-arylsulfanylcoumarins were generated under extremely mild conditions on solidphase with a silyl linker based macro-beads by base-promoted reaction of 4-tosyloxycoumarins with thiols.
