Intramolecular cross-ring enone–alkene photoannelation in 6-(ω-alkenyl)-cyclohex-2-en-1-ones
Abstract
The irradiation of some 6-(ω-alkenyl)-cyclohex-2-en-1-ones in micelles gave a carbonyl bridged intramolecular photoadduct but the reaction is restricted to enones tethered to an alkene by not more than a four-carbon chain.
