Development and Scope of the

2-Formylpyridines have been shown to be suitable electrophiles for the magnesium-promoted phenolic aldol reaction. Exceptionally mild reaction conditions have been developed and a brief survey of the reaction scope has been conducted. This process gives straightforward access to a range of functionalised 2-hydroxyphenyl-2-pyridylmethanols and 2-hydroxyphenyl-2-pyridylmethanes via their subsequent reduction.
2′-Hydroxyphenylpyridinemethanols 7 were synthesized by metal-templateortho-regioselective alkylation of phenols 5 with 2-, 3- and 4-pyridinealdehydes 6.
