抄録

The Stereoselective one-pot synthesis of cis-fused pyrano and furanobenzopyrans has been developed from <I>o</I>-hydroxybenzaldehydes, aromatic amines, and cyclic enol ethers in the presence of Bi(OTf)<SUB>3</SUB> in air- and moisture-stable ionic liquid, [bmim]PF<SUB>6</SUB> under mild conditions. The recovered ionic liquid containing Bi(OTf)<SUB>3</SUB> can be reused three to five subsequent runs with only a gradual decrease in activity. The recovery of catalyst is facilitated by its hydrophobic nature of [bmim]PF<SUB>6</SUB>.
