Descrizione generale

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

Applicazioni

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.

N(2)-isobutyrylguanine was prepared by treatment of guanine with isobutyryl chloride. Two tautomers, 1,7-dihydro-2-(isobutyroyl)amino-6H-purin-6-one and 1,9-dihydro-2-(isobutyroyl)amino-6H-purin-6-one, were identified in almost 1:1 ratio in dichloromethane-dimethyl sulfoxide (1:1 v/v) by NMR spectroscopy.
