A Novel Oxidative Intramolecular (4+2)Cycloaddition of Silylene-Protected Dihydroxystyrene Derivatives Leading to peri-Hydroxy Polycyclic Aromatic Compounds: A Synthesis of the ABCD Ring.
A novel intramolecular [4+2] cycloaddition of silylene protecting dihydroxystyrene derivatives: A versatile synthesis of linearly condensed -hydroxy aromatic compounds
The first example of an intramolecular [4+2] cycloaddition of the silylene protecting dihydroxystyrene derivatives leading to linearly condensed -hydroxy aromatic compounds (6a–c) is described.
