Organocatalytic Asymmetric Synthesis of Spiro-Bridged and Spiro-Fused Heterocyclic Compounds Containing Chromane, Indole, and Oxindole Moieties.

open access: yesOrganic Letters, 2018
Following the reactivity inversion strategy, two different two-step sequences were designed and successfully applied to the asymmetric synthesis of spiro-bridged and spiro-fused heterocyclic compounds, which combined chromane, indole, and oxindole, three

Nazarov Cyclization/Internal Redox Cyclization Sequence for the Synthesis of N-Heterocyclic Bridged Ring Systems.

open access: yesOrganic Letters, 2016
A 1,6 conjugate addition/Nazarov electrocyclization/internal redox cyclization sequence was developed. Various 5-hydroxycyclopentenones were made through the 1,6-conjugate addition initiated Nazarov reaction with excellent diastereoselectivities.
