Synthesis of silyloxyacrolein for [4+3] cycloaddition and preparation of carbonate closomer
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Followed by Funk's method, I synthesized silyloxyacroleins and used them as dienophiles to react with different dienes in [4+3] cycloaddition reaction. These enals such as 2...
Studies on the nucleophilic substitution reactions of a dimeric cyclopentadienone
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Nucleophilic substitution reactions of 3,5-Dibromo-3a,4,7,7a-tetrahydro-4,7-methano-indene-1,8-dione (48) have been studied. Amines, thiols and alcohols have been employed...
Oxidation & 1, 5-hydride shift of sulfoximine derivatives
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Oxidation of N-alkyl and N-aryl sulfoximines and 1,5-hydride shift of S-alkenyl sulfoximines have been studied. Oxidation of N-alkyl sulfoximines using dimethyldioxirane gave...
Studies of 2,1-benzothiazine, silver-catalyzed rearrangement and 1,5-hydride shift
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Dimethyl sulfoximine was used to synthesize benzothiazines by coupling reaction. When the substrate is dibromodibenzaldehyde, water was added to complete the reaction in meso...
Studies of the chemistry of Tröger's base, cyclopentadienones, and 2,1-benzothiazines
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The sequential alkylation of Tröger's base was developed for the synthesis of symmetric dialkylation analogs. The products from this reaction were obtained in reasonable yields...
Study of the chemistry of 2,1-benzothiazines and toward the total synthesis of elisapterosin B
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Using enantiomerically pure benzothiazines as templates, enantiomerically pure cyclobutanes were prepared. Such compounds are potentially interesting synthetic intermediates...
