Electrophilic fluorine-mediated dearomative spirocyclization has been developed to synthesize a range of fluoro-substituted spiro-isoxazoline ethers and lactones. The in vitro biological assays of synthesized compounds were probed for anti-viral activity against human cytomegalovirus (HCMV) and cytotoxicity against glioblastomas (GBM6) and triple negative breast cancer (MDA MB 231). Interestingly,

A series of 4-alkyl-5-aminoisoxazoles have been synthesized in high yield by nucleophilic addition of lithiated alkyl nitriles to (alpha)-chlorooximes. The scope and limitations of this reaction were examined by varying the nature of the nitrile and chloride oxime.

Glucosinolates are naturally occurring plant compounds that may be important in the dietary prevention of cancer. This study shows that they can be detected in their intact form by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) with a high degree of sensitivity. The methodology was used to characterize a number of individual glucosinolates either produced by synthetic chemistry or isolated from plants. The method was used for crude plant extracts to rapidly examine the glucosinolate profile of the plant. The results for a range of plant extracts showed good agreement with previous LC-MS analysis of the desulfoglucosinolates from the same samples.

This invention relates to a process for preparing N-hydroxyl organo imidate compounds by reacting an oxime compound with a halogenating agent and reacting the resulting 1-halosubstituted oxime compound with the alkali metal or alkaline earth metal salt of an alcohol.
