Ynamines derived from nucleic acids bases: synthesis, reactivity and biological activity

Abstract

Ynamines 1a–d are prepared by alkylation of nucleic acids bases with tetrachloroethylene followed by elimination of halogens from the intermediates 4a–d; reaction of 1a with acetone and cyclohexanone gives carbinols 8a and b and in the case of 8b cyclic ketal 9a is also obtained; compound 1a is a substrate for adenosine deaminase.
