Abstrakt:	A simple and efficient method has been developed for the synthesis 2-(2-hydroxyphenyl)-4-arylpyridines annulated by C5-C6 cycles with substituted benzylidene group is achieved by multi-component Kröhnke-type reaction with moderate to good yields in PEG-400. The classical version was considered using cross-conjugated dienones as substrates by counter synthesis. [ABSTRACT FROM AUTHOR]
