Switching of Product's Chirality in Diastereodifferentiating [2+2] Photocycloaddition of (E)- versus (Z)-Stilbene to Chiral Fumarate upon Direct and Charge-Transfer-Band Excitation

Autor: Hideaki Saito, Yoshihisa Inoue, Takehiko Wada, Tadashi Mori

Publikováno v: Organic Letters. 8:1909-1912

[reaction: see text] Diastereodifferentiating [2+2] photocycloadditions of (E)- and (Z)-stilbenes to bis((R)-1-methylpropyl) fumarate were performed through the direct excitation of stilbenes and the selective excitation of the charge-transfer (CT) c

Cyclization Pathways of a (Z)-Stilbene-Derived Bis(orthoquinone monoketal)

Autor: Ken S. Feldman

Publikováno v: The Journal of Organic Chemistry. 62:4983-4990

Lead tetraacetate mediated oxidation of a (Z)-bisphenolic stilbene derivative affords a bis(orthoquinone monoketal) product. Thermolysis studies of this highly unsaturated dione reveal that sigmatropic hydrogen shifts, followed by either of two disti

Elemental sulfur reactions with toluene, dibenzyl, Z-stilbene and their geochemical significance

Autor: E. Malinski, K. Przewocki, J. Szafranek

Publikováno v: Chemical Geology. 47:347-360

The reaction of elemental sulfur with toluene (at 200°C) was studied in an atmosphere of an inert gas (Ar), with either oxygen or water present. The products arising at different periods were identified by GC—MS. The structures of some of them wer

Use of dibenzophosphole oxides in the Horner reaction: stereospecific formation of (Z)-stilbene from an erythro-β-hydroxyalkylphosphine oxide

Autor: Tony G. Roberts, Gordon H. Whitham

Publikováno v: J. Chem. Soc., Perkin Trans. 1. :1953-1955

Treatment of the erythro-β-hydroxyalkyldibenzophosphole oxide (6), derived from (E)-stilbene oxide and lithiodibenzophosphole, with 1,5-diazabicyclo[5.4.0]undec-5-ene (DBU) in dimethyl sulphoxide (DMSO) affords (Z)-stilbene with high stereospecifici
