General description
The mechanism of esterification of 1-(1-naphthyl)ethanol by isobutyric anhydride with 4-pyrrolidinopyridine as catalyst was studied.
Application
Isobutyric anhydride was used in the synthesis of 4-O-isobutyryl derivative via reaction with octyl β-D-glucopyranoside in the presence of C2-symmetric chiral 4-pyrrolidinopyridine as a catalyst.
