Transition-metal-free [3+3] annulation reaction of sulfoxonium ylides with cyclopropenones for the synthesis of 2-pyrones
An efficient and practical synthetic approach was developed for the tandem synthesis of trisubstituted 2-pyrone derivatives from sulfoxonium ylides and cyclopropenones. This [3+3] annulation reaction was carried out under transition-metal-free conditions. A broad range of functional groups were tole...
