Synthesis and biological activity of cyclohexenyl nucleosides. cis-5-(9H- purin-9-yl)-3-cyclohexenyl carbinols and their 8-azapurinyl analogs
5-Azido-3-cyclohexenecarboxylic acid was reduced to an aminocyclohexenylcarbinol which was coupled with either 5-amino-4,6- dichloropyrimidine or 2-amino-4,6-dichloropyrimidine, giving 5-pyrimidinyl- 3-cyclohexencarbinols. Condensation with triethylorthof
