Description

General description

(Trimethylsilyl)diazomethane, a methylating agent, is generally used for the methylation of carboxylic acids. It is also used as a derivatization agent for the analysis of carboxylic acids and polyphenols by the GC-MS method.

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

Synthetic applications include metathesis and cycloaddition reactions.
Regioselective dipolar cycloadditions to give amino acids and azakainoids.

Preparation Note

Preparation of substituted cyclopentenones via [4+1] annulation with vinylketenes.
