✦ Synopsis

Intramolecular Hydroalkoxylation in Broensted Acidic Ionic Liquids and Its Application to the Synthesis (±)-Centrolobine (XXIb). -The novel ionic liquids (I)-(III) are similarly effective in initial studies, but (Ia) and (II) are more effective in large-scale reactions. They are used in catalytic and stoichiometric amounts leading to a variety of substituted furan or pyran structures. They can be recycled up to 3 times without significant loss of activity. -(JEONG, Y.; KIM, D.-Y.; CHOI, Y.; RYU*,
