N2,9-Diacetylguanine Chemical Properties,Usage,Production

Description

N2,9-Diacetylguanine is a purine compound that can be prepared by acetylation of guanine with acetic anhydride. It can be used in many fields such as organic synthesis, biological research and pharmaceutical manufacturing. N2,9-Diacetylguanine can be prepared into 2-amino-6-halogenated purine under the action of two-step PEG-2000 phase transfer catalyst and TPPB phase transfer catalyst, and further through the corresponding CuX-catalyzed diazotization reaction, new 2-halogenated purine compounds can be efficiently synthesized^[2]. In addition, it can also be used as an intermediate for the antiviral drugs Ganciclovir and Aciclovir.

Chemical Properties

white or brownish crystalline powder

Uses

N2,9-Diacetylguanine (Acicclovir EP Impurity L) is used to synthesize acyclic analogues of deoxyguanosine.

Application

The alkylation of N2,N9- diacetylguanine (DAG) with 2-oxa-1, 4-butane-dioldiacetate to give N2-acetyl-9-{2-acetoxyethoxymethyl}- guanine (N9 isomer) and/or N2-acetyl-7-{2-acetoxyethoxymethyl}- guanine (N7 isomer) in exceptionally high regioselectivity[1].
