First synthesis of simple optically active selenoxides

Autor: Joanne M. Billmers, Franklin A. Davis, Orum D. Stringer

Publikováno v: Tetrahedron Letters. 24:3191-3194

Simple optically active selenoxides (5-11 %e.e.) were prepared using a kinetic resolution procedure and were demonstrated to be configurationally unstable as a result of acid catalyzed achiral hydrate formation.

Asymmetric oxidation of achiral selenides to optically active selenoxides

Autor: Orum D. Stringer, Franklin A. Davis, John P. McCauley

Publikováno v: Tetrahedron. 41:4747-4757

Asymmetric oxidation of methyl phenyl selenide ( 3 ), under anhydrous conditions, by chiral 2-sulfonyloxaziridines, 1–2 , gives optically active methyl phenyl selenoxide (8.1–9.3% ee). The stereochemistry of the selenoxide is determined by the co

Synthesis and evaluation of non-catechol D-1 and D-2 dopamine receptor agonists: benzimidazol-2-one, benzoxazol-2-one, and the highly potent benzothiazol-2-one 7-ethylamines

Autor: William A. Mann, Lewis B. Kinter, Robert G. Franz, Orum D. Stringer, J. Paul Hieble, George W. Gessner, Joseph Weinstock, K. E. Flaim, Dimitri Gaitanopoulos

Publikováno v: Journal of medicinal chemistry. 30(7)

Our interest in identifying D-1 and D-2 dopamine receptor agonists that are not catechols led us to extend previous studies with oxindoles by investigating analogues of dopamine, N,N-dipropyldopamine, m-tyramine, N,N-dipropyl-m-tyramine, and epinine
