AI Article Synopsis
- Quaterpyridines are important in metallo-supramolecular chemistry, but their synthesis often involves sensitive components.
- The authors outline a method to synthesize nonsymmetric quaterpyridines with 70-85% yields using enones and a specific terpyridine through a Kröhnke pyridine synthesis.
- They also describe a straightforward way to produce the starting material, 6-acetyl-2,2':6',2''-terpyridine, and present X-ray analysis of a chiral quaterpyridine and its platinum complex.
Article Abstract
Quaterpyridines have been demonstrated to be useful building blocks in metallo-supramolecular chemistry; however, their synthesis requires the preparation of sensitive building blocks. We present here three examples of nonsymmetric quaterpyridines that were easily obtained in yields of 70-85% by condensation of commercially available enones with 6-acetyl-2,2':6',2''-terpyridine through a Kröhnke pyridine synthesis. Easy access to 6-acetyl-2,2':6',2''-terpyridine starting from 2,6-diacetylpyridine and 2-acetylpyridine is described. The X-ray analysis of a chiral quaterpyridine and its Pt(II) complex is presented.
