The present invention provides a retinoid-related receptor (except retinoic acid receptors) function regulating agent comprising a compound represented by the formula:
1
wherein one of R
1
and R
2
is an optionally substituted monocyclic aromatic hydrocarbon group or an optionally substituted monocyclic aromatic heterocyclic group containing one heteroatom, and the other is a hydrogen atom and the like; B is a 5- or 6-membered heterocycle (except 1,3-azole); A is an optionally substituted aromatic hydrocarbon group or an optionally substituted aromatic heterocyclic group; and R
3
is a hydrogen atom and the like, or a salt thereof, which is useful as an agent for the prophylaxis or treatment of diabetes mellitus, hyperlipidemia, impaired glucose tolerance or the like.

A protocol for the synthesis of highly substituted 2,4‐diacypryrroles via a copper‐catalyzed ring strain releasing dimerization reaction was developed. The pyrroles are synthesized combining UV–photochemistry and metal‐catalyzed follow up reaction in an one‐pot system. To match the rates of the thermal and the photoinduced step, an internal temperature control was established.
