Surprising reaction of 3-(2-chloro-ethyl)pyrido[3',2':4,5]thieno[3,2-d]pyrimidinones with α,ω-diamino-alkanes to tetracyclic compounds with an anellated dihydroimidazo-, dihydropyrimido- or tetrahydro-1,3-diazepino-ring

Bis- and monoacylated compounds of structure B reacted with ω-hydroxyalkylamines to give the tricyclic 3-(ω-hydroxy-alkyl)pyrido[3',2':4,5]thieno[3,2-d] pyrimidin-4-(3 H)-ones. The title compounds were obtained by the reaction of the 3-(2-chloroethyl) der
