A novel and convenient synthesis of 1-naphthaldehydes through iodinemonochloride promoted cascade reactions of 1-phenylpent-4-yn-2-ols is presented. Compared with literature procedures, this new method has advantages such as simple operation procedure, mild reaction conditions, good efficiency, and excellent regio-selectivity.

of 1-arylpenta-3,4-dien-2-ones with activated ketones allowed for an efficient and sustainable synthesis of 2-arylphenols. Moreover, this reaction was also found to be compatible and combinable with Pd-catalyzed C-Hactivation and carbonylation of the in situ formed 2-aryl phenols, thus resulting in a highly convenient and atom-economic synthesis of dibenzopyranones.
