General description

(Trimethylsilyl)diazomethane is considered as a non-explosive substitute to diazomethane for the homologation of carbonyl derivatives, mainly ketones, via reactions such as Tiffeneau-Demjanov rearrangement.

Application

Reactant for preparation of:
  • Macrolactam analogs of the natural product macrolide (-)-A26771B with improved metabolic stability and antibacterial activity
  • Aigialomycin D analogues as protein kinase inhibitors for cancer treatment
  • Unnatural α-amino acid derivatives containing gem-bisphosphonates via Michael addition reaction
  • Capped 4-methylumbelliferyl hyaluronan disaccharides and tetrasaccharides as potential hyaluronidase substrates
  • Stictamides A-C as matrix metallopeptidase 12 (MMP12) inhibitors with antitumor invasion activity
  • Endothelin converting enzyme (ECE) Inhibitors WS 75624A and WS 75624B via a cross-metathesis approach
  • Ent-kaurene derivatives as anti-inflammatory agents
  • Desmosdumotin C analogs as potent antitumor agents acting via activation of spindle assembly checkpoint
  • Imidazolo[2,1-b]benzothiazole derivatives as potential p53 inhibitors
