Trimethyl orthobutyrate Chemical Properties,Uses,Production
Chemical Properties
Clear colorless to slightly yellow liquid
Uses
Trimethyl orthobutyrate has been used in the preparation of:
- 5-acetamido-9-O-butyroyl-3,5-dideoxy-D-glycero-2-nonulo pyranosonic acid
- 9-O-butyroyl-3,5-dideoxy-5-glycoloylamido-D-glycero-2-nonulo pyranosonic acid
Uses
Trimethyl orthobutyrate can be used for:
- Acylation at OH-9 of N-acetylneuraminic acid and N-glycoloylneuraminic acid to give the corresponding 9-O-acylated derivatives.
- Conversion of 2-amino-N-(1-H-benzimidazol-2-yl)benzamide to 2-propyl-3-benzimidazolyl-4(3H)-quinazolinone.
- Preparation of 2-propyl substituted benzimidazoles from 1,2-benzenediamines.
It can also be used in the total synthesis of dl-camptothecin, Olmesartan Medoxomil, DE and CDE ring analogs of camptothecin, and homologs of 1,25-dihydroxyvitamin D3.
General Description
Kinetics and mechanism of gas-phase elimination of trimethyl orthobutyrate has been examined over the temperature range of 310-369°C and pressure range of 50-130Torr.
