Water-Catalytic Deconstructive and Proton Transfer Cyclopropanation of Sulfoxonium Ylide with Olefin. [PDF]
Adv Sci (Weinh)Water‐catalytic deconstructive and proton transfer cyclopropanation of sulfoxonium ylide with olefin is developed through a sequential water‐mediated ring‐closing/opening reaction. This atom‐economical, environmentally friendly methodology offers easy access to a range of cyclopropyl ketones with moderate to good yields.

Trace evidence of trans-phenylpropene as a marker of smoked methamphetamine. [PDF]
Journal of Analytical Toxicology, 2008 This case study investigates trans-phenylpropene as a potential marker for smoked methamphetamine. The decedent, a 31-year-old male, was found with paraphernalia that indicated that he may have been smoking abused drugs prior to death. Methamphetamine and cocaine were detected in the residue remaining in the paraphernalia.
