1. (4+2) -Cycloadditions of nitrosoalkenes, vinylnitrosonium cations, and nitroalkenes are discussed.

The {3,3}sigmatropic rearrangement of N-alkyl-N-aryl-O-acetoacetylhydroxylamines gives N-alkyl indoles in moderate yields under mild conditions. The substituted hydroxylamines were prepared by the condensation of aldehydes ...

Format and number of attempts were varied in online pre-lecture quizzes administered to a first semester non-majors organic chemistry lecture course. Student quiz performance and post-quiz assessment shows significant ...

The transition state geometry for the transfer of oxygen from N-sulfonyl oxaziridines to alkenes and fluorine transfer from N-fluoro sultams to carbanions was investigated. In the former application of the endocyclic ...

A structure-activity study was done on a series of 6-halo-2-pyranones as suicide inhibitors of chymotrypsin. In the 6-chloro-2-pyranone series, substitution in the 3- position of the pyrone by either ethyl or n-butyl ...

Presented here are elastic neutron scattering pressure studies investigating the magnetic ordering of KCuF3 under hydrostatic pressure. Recent studies have predicted the magnetic ordering to be modified at P ~ 7 kbar due ...

Biological phenomena, while grounded in the laws of physics and chemistry, often exhibit behaviours too complex to be ascribed to a single electron density, bond vibration or chemical reaction. Rather, the processes inherent ...
