Description

General description

Isobutyryl chloride reacts with guanine to yield N(2)-isobutyrylguanine.

Application

Isobutyryl chloride was used in the synthesis of fully isobutyramide terminated hyperbranched polyethylenimines. It was used in the separation and identification of shikonin and its ester derivatives in the root epidermis of Echium italicum L. It was employed as versatile acylating agent for the ketimine derivatives of α-amino esters, nucleosides and pyrroles.

Versatile acylating agent for the ketimine derivatives of α-amino esters, nucleosides, and pyrroles.
