A simple and efficient one‐pot synthesis of 6‐bromocoumarins was achieved in good yields via the three‐component reaction of phenols, 4‐substituted acetoacetate and tetrabutylammoniumtribromide (TBATB) in CH2Cl2‐MeOH.
Synthesis and photochemical properties of new photoremovable protecting groups for nucleobases are described. Four caged 2'-deoxycytidines (dCs) were synthesized, and their photochemical properties were measured under simulated physiological conditions. Two new coumarin-caged dCs show better photochemical and photophysical properties than those of the caged dCs having previously reported caging groups.

Development of 6-arylcoumarins as nonsteroidal progesterone antagonists. Structure–activity relationships and fluorescence properties
showed more potent PR-antagonistic activity than lead compounds 5 (IC50: 500 nM) and 6 (IC50: 65 nM) in alkaline phosphatase (AP) assay. Compound 9b showed solvent-dependentfluorescence intensity, exhibiting strong fluorescence in the presence of PR LBD only in buffer solution. On the other hand, 10b showed a solvent-dependent shift of the fluorescence maximum wavelength in the presence of PR LBD. These
