摘要：A convenient palladium-catalyzed tandem reaction of aryl iodides and salicyl N-tosylhydrazones has been achieved to afford a series of compounds containing the novel spiro[benzofuran3,2'-chromene] scaffold in moderate to good yields. This efficient catalytic reaction, which tolerates various functional groups, combines alkyne-based 5-exo-dig cyclization, palladium(II) carbene migratory insertion and intramolecular cyclization, generating three new bonds in one reaction.
