Abstract
Synthetic transformations of the products of the Achmatowicz rearrangement with potassium organotrifluoroborates in the absence of transition metals provide dihydropyranones (2,6-trans), tetrahydropyranones (2,3-cis-2,6-cis) or functionalized 1,4-dicarbonyl compounds depending on the reaction conditions and the substitution pattern. The method has also been adapted for the one-pot synthesis of functionalized pyrroles.
