Abstract
2-, 3-, or 4-Picolyllithium was prepared in excess lithium diisopropyl amide and condensed with several hydroxy-benzaldehydes and 4-hydroxyac etophenone to afford substituted hydroxyphenyl-pyridyl-ethanols and al pha-hydroxyphenyl-alpha-methylpyridineethanols. In two instances, 3-pi colyllithium condensed with aldehydes to presumably form the hydroxyph enyl-pyridyl-ethanol, which underwent linear dehydration to the substi tuted pyridyl-ethylenyl-phenol.
