Reactions of adenine with ethylene oxide and propylene oxide

Abstract

Reactions leading to thermostable polyetherols containing purine rings were studied. Products of reaction of adenine and an excess of the oxiranes were analyzed by proton nuclear magnetic resonance and infrared spectroscopies. The physical properties of some of the products were determined.

Preparation of new polymers from heterocyclic compounds and reactive solvents of melamine

“…ref. 12), but two signals of CH groups could be seen at 8.9 and 9.7 ppm. The same signals were present in the spectrum of the hydroxymethyl derivative of adenine (Fig.…”

A One-pot Multicomponent Reaction for the Synthesis of Oligoetherols with Azacyclic Rings

“…1,2 These oligoetherols can be applied to form rigid polyurethane foams (PUFs) of enhanced thermal resistance due to the presence of above mentioned rings. Oligoetherols can be obtained from IA, MEL or adenine and excess oxiranes like ethylene oxide (EO) or propylene oxide (PO) [3][4][5] or from the reaction of alkylene carbonates (AC) with the mentioned azacylic compounds. 2 General reaction pathway is shown in Scheme 2.…”
