  Synthesis of Functionalized Chromanes via a Formal [3+3]Cycloaddition of Allene Sulfonamides to Phenols

  摘要：

  The Bronsted acid catalyzed formal [3 + 3] cycloaddition reaction of allene sulfonamides l with phenols 2 provides functionalized chromanes. This formal [3 + 3] cycloaddition reaction is proposed to proceed via a stepwise process involving intermolecular hydroarylation followed by intramolecular cyclization.
