Abstract
The preparation and properties of N-acylated derivatives of guanine, 2-amino-6-purinethiol and their related compounds were described. The position of the N-acyl group introduced was deduced to be the 2-amino group of purine ring from the elemental analysis and the comparison of ultraviolet spectra of related compounds. During the acylation procedure, desulfurization of 2-amino-6-purinethiol and alkyl substituted compound was observed.
