Trimethyl orthobutyrate Chemical Properties,Usage,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.
