Abstract

Bis‐1,2,3,4‐tetrahydropyrimidinylalkanes/benzenes 2a‐f have been synthesized by the reaction of N,S‐acetals with formaldehyde and diamines. Reaction of pyrazoles 3a and 3b with diamines and formaldehyde yield bis‐4,5,6,7‐tetrahydropyrazolo[3,4‐d]pyrimidinylalkanes 4a‐b and bis‐1,2,3,4‐tetrahydropyrazolo[1,5‐a]triazinylalkanes and benzene 5a‐c respectively in good yields.
