Abstract

A series of partially hydrogenated imidazo[1,2-<i>c</i>]pteridines <i>IXa – IXc, XIa - XIf</i> and <i>XVa - XVc</i>, pyrimidol[1,2-<i>c</i>]pteridines <i>XIIa - XIId</i> and <i>XVIa - XVIc</i>, and 1,3-diazepinol[1,2-<i>c</i>]pteridines <i>XIIIa - XIIIc</i> and <i>XVII</i> have been prepared from 2-amino-3-cyanopyrazines <i>I</i> via reactions of <i>I</i> with alkanediamines <i>II - IV</i> and subsequent condensation of the resulting intermediates <i>V - VII</i> with orthoesters <i>VIII</i>, aldehydes <i>X</i> and ketones <i>XIV</i>.
