—— | (6,7-Dimethyl-2-oxochromen-4-yl)methyl acetate | 485821-94-1 | C14H14O4 | 246.263 |
The palladium-catalyzed nucleophilic substitution of (coumarinyl)methyl acetates is described. The reaction proceeds though a palladium π-benzyl-like complex and allows for many different types of C-, N-, and S-nucleophiles to be regioselectively added to the biologically active coumarin motif. This new method was utilized to prepare a 128-membered library of aminated coumarins for biological screening.
