Vinylcyclopropanation of enones in [2+3] cyclopentene annulation: application to the total synthesis of (-)-retigeranic acid
… annulation process. [see document for diagram of chemical compounds] The reactions of 161a with other electrophiles such as ketones, α,ß-unsaturated esters and α,ß-unsaturated aldehydes were also investigated. The possibility of asymmetric induction utilizing (-)-menthyl 2-bromocrotonate (169) was …

Analysis and interpretation of high-throughput chemical-genetic interaction screens.
Screening chemical compounds against genome-wide mutant arrays identifies genetic perturbations that cause sensitivity or resistance to compounds of interest. The resulting chemical-genetic interaction profiles contain information on the cellular functions perturbed by compounds and can be used to …

The fate and distribution of subsurface hydrocarbons released during the 2010 MC252 oil spill in deep offshore waters of the Gulf of Mexico
… in history. In this study, the distribution and chemical composition of hydrocarbons within a 45 km radius of the blowout was investigated. A complete set of hydrocarbon data were acquired from the National Oceanic and Atmospheric Administration (NOAA) and from BP, including data from 16 research …
