2,3-epoxyalcohols are shown to undergo stereoselective reactions in the presence of tin tetrachloride. The resulting diols when treated with acid are converted into polycyclic aromatic hydrocarbons or polycyclic ketones.
Functionalized angular cycloalkane-fused naphthalenes were prepared using a two-step process involving a Pd-catalyzed Suzuki–Miyaura coupling of aryl pinacol boronates and vinyl triflates followed by a boron trifluoride etherate-catalyzed cycloaromatization.
