In the title molecule, C 18 H 25 N 3 O 2 S, the central thienopyrimidine ring system is essentially planar. The cyclohexene ring, in which the four CH 2 groups are disordered in an approximately 1:1 ratio, adopts a half-chair conformation, while the morpholine ring is in a standard chair conformatio
## Abstract magnified image A series of novel 7‐alkyl/aryl sulfonyl‐4‐pyrrol‐1‐yl‐5,6,7,8‐tetrahydro‐pyrido[4′,3′:4,5]thieno[2,3‐d] pyrimidine **6** were synthesized for evaluation of their antibacterial and antifungal activity. The structures were determined by IR, NMR, mass spectroscopy, and ele
