A totally stereoselective synthesis of (Z)-2-arylidene-1,4-benzodioxanes using palladium–copper catalysis
摘要:
A convenient and general synthesis of (Z)-2-Arylidene-1,4-benzodioxanes from a mono-prop-2-ynylated catechol and aromatic halides by palladium catalysis is described.

A novel palladium(0)‐catalyzed dearomative cyclization reaction of bromophenols with (1,n)‐diynes has been developed for building two new types of tricyclic architectures containing a quaternary carbon center. This method employs inexpensive bromophenols, and easily accessible tethered diynes. It exhibits a broad substrate scope and tolerates various functional groups. Preliminary results with commercially
