Abstract
Abstract New enantiopure pyridyl alcohols are efficiently accessible through few synthetic steps from commercially available terpenes, that is,(+)-fenchone,(−)-menthone and (−)- verbenone as well as 2, 6-diphenylpyridine. These chelating pyridyl alcohols exhibit flexible pyridyl–phenylene axes, which give rise to P and M conformers. Alkylzincation of the hydroxy groups eliminates equilibria of the conformers and generates alkylzinc complexes ...
