Unprecedented reductive dealkoxylation of aryl alkyl ethers and intramolecular C–C coupling of 2,2′-dialkoxystilbenes with low valent titanium: one-pot synthesis of phenanthrenes
Abstract
Facile dealkoxylation of aryl alkyl ethers has been carried out using TiCl3–Li–THF (tetrahydrofuran); a novel one-pot synthesis of phenanthrenes from ortho-alkoxyaromatic aldehydes/ketones is described.
