Stereochemistry of the Thermal Isomerization of 1-Ethenyl-7-exo-Phenylbicyclo[4.1.0]heptane to 7-Phenylbicyclo[4.3.0]non-1(9)-ene: The Conformational Course of an Antarafacial,Retention Vinylcyclopropane-Cyclopentene Rearrangement

The thermal vinylcyclopropane-cyclopentene rearrangement of 1-ethenyl-7-exo-phenylbicyclo[4.1.0]-heptane at 220°C gives mostly migration with retention to form 7-exo-phenylbicyclo[4.3.0]non-1(9)-ene. 1-(E-d-Ethenyl)- and 1-(Z-d-ethenyl)-7-exo-phenylbicyclo[4.1.0]heptanes give both 8-exo and 8-endo deuterium-labeled products. The suprafacial,retention and antarafacial,retention paths for this rearrangement are used in 85:15 proportions. The antarafacial process may involve passage through a "semicircular" diradical conformation; it cannot occur through rotation in the opposite sense, passing through an "extended" diradical geometry.

The reaction of PhI=NTs with sulfoxides in the presence of catalytic amounts of CuOTf afforded the corresponding N-tosylsulfoximines in high yield. The use of enantiomerically pure sulfoxides allowed stereoselective access to N-tosylsulfoximines with comp

N-(Arenesulfonyl)sulfilimines can be oxidized to the corresponding sulfoximines in high yields with sodium hypochlorite in an AcOEt-H2O two phase system in the presence of quaternary ammonium salts as catalysts.
