Anwendung
Trimethylboroxine (TMB) is a cyclic anhydride of methyl-boronic acid. It can be used as a:
- Methylating agent for the methylation of various aromatic halides and C(sp3)−H bonds using palladium catalyst.
- Reagent in the preparation of polymer supported CBS (Corey, Bakshi, and Shibata) catalysts.

We present a strategy to rationally prepare CF3- transfer reagents at ambient temperature from HCF3. We demonstrate that a highly reactive CF3- adduct can be synthesized from alkali metal hydride, HCF3, and borazine Lewis acids in quantitative yield at room

Spinal muscular atrophy (SMA) is the leading genetic cause of infant death. We previously developed a high-throughput assay that employs an SMN2-luciferase reporter allowing identification of compounds that act transcriptionally, enhance exon recognition, or stabilize the SMN protein. We describe
