The [2,3]-sigmatropic rearrangement of propargylic sulfonates to allenic sulfones and further applications to oxacycles and dihydrofuranones
(University of Missouri--Columbia, 2015)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The scope of [2,3]-sigmatropic rearrangement of propargylic sulfinates to allenic sulfones by silver catalysis was expanded. A series of new propargylic ... -
(4+3)-cycloaddition chemists of oxidopyridinium ions and related study
(University of Missouri--Columbia, 2019)The (4+3)-cycloaddition reaction is a cycloaddition between a 4-atom species and a 3-atom species to form a seven-membered ring. This reaction results in the formation of seven-membered rings. Our research expanded the ... -
Intermolecular (4+3) cycloaddition reaction of oxidopyridinuim ions with silylated dienes, exploring the oxidation chemistry and photochemistry of cycloadducts
(University of Missouri--Columbia, 2022)The development of endo/exo selectivity of intermolecular (4+3) cycloaddition reactions of an N-methyl oxidopyridinium ion has been studied. Dienes that contain silyl groups, R-groups, and contain both silyl group and ... -
Intramolecular (4 + 3) cycloadditions of oxidopyridinium ions : towards daphnicyclidin A
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 5/1/2024] N-alkylation of alkyl 5-hydroxynicotinates with electrophiles containing diene functionality produces salts , which can undergo intramolecular (4 + 3) cycloaddition reactions when heated in the ... -
Stereoselective synthesis of seven-membered rings using intramolecular (4+3) cycloaddition reactions
(University of Missouri--Columbia, 2020)Heterocyclic molecules containing seven-membered rings have importance in organic synthesis owing to their presence in some natural products and biologically active molecules. Furthermore, these scaffolds act as important ...
