Atom-Economic Synthesis of 4-Pyrones from Diynones and Water
preprint
OA: closed
Abstract
Transition-metal-free synthesis of 4-pyrones via TfOH-promoted nucleophilic addition/cyclization of diynones and water has been developed. This transformation is simple, atom economical and environmentally benign, providing rapid and efficient access to substituted 4-pyrones.
