Imidazole compounds having adenosine deaminase inhibitory activity represented by the formula (I) wherein R1 is aryl or heterocyclic group which is optionally substituted with substituent(s); R
2
is lower alkyl; R
3
is hydroxy or protected hydroxy; -A- is lower alkylene; and —X—is —O— or —S—; provided that when then R1 is aryl which is substituted with substituent(s), or heterocyclic group which is optionally substituted with substituent(s), its prodrug, or their salt. The compounds are useful for treating and/or preventing diseases for which adenosine is effective.

A conceptuallynewsynthesis of pyridine rings by a [C4 + CN] assembly has been developed by applying a vinylogous version of the classic Blaisereaction. The zinc-mediated reaction of (het)aryl or alkyl nitriles with ethyl-4-bromocrotonate provided a variety of C(6)-substituted pyridin-2-ones in a single-step.
