Pd(0)-catalyzed chemoselective construction of spirocarbocycles via an alkyne insertion/β-naphthol dearomatization cascade†
Abstract
A microwave-assisted Pd(0)-catalyzed alkyne migratory insertion/β-naphthol dearomatization cascade process has been accomplished to access a variety of spirocyclic compounds bearing all-carbon quaternary stereogenic centers in high yields with excellent chemoselectivities.
