3H-萘并[2,1-b]吡喃-3-酮,1-[(乙酰氧基)甲基]- | Acetic acid 3-oxo-3H-benzo[f]chromen-1-ylmethyl ester | 106236-97-9 | C16H12O4 | 268.269 |
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.
