PALLADIUM-CATALYZED INTRAMOLECULAR HYDROARYLATION OF 6-BENZOFURANYL ALKYNOATES
摘要:
Intramolecular hydroarylation of 6-benzofuranyl alkynoates efficiently proceeded using Pd(OAc)(2) as catalyst in TFA and CH2Cl2 at room temperature. This intramolecular hydroarylation gave a mixture of regioisomers of furocoumarins, i.e., psoralens and allopsorallens.
