The Journal of Organic Chemistry, vol. 83, n.o 18, septiembre de 2018, pp. 11425-36.

Depending on the reaction conditions and the substitution pattern of the starting material, the reaction may lead to the stereoselective synthesis of dihydropyranones (2,6-trans), tetrahydropyranones (2,3-cis-2,6-cis) or functionalized 1,4-dicarbonyl compounds. The method has also been adapted for the one-pot synthesis of functionalized pyrroles.engjournal articlehttps://doi.org/10.1021/acs.joc.8b01643https://pubs.acs.org/doi/10.1021/acs.joc.8b01643restricted access547Química orgánica (Química)2306 Química Orgánica
