Application

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.
