Synthesis of β-substituted chalcones from phenones via conjugated nucleophilic substitution of propargylic alcohols
Phenones can be efficiently transformed into β-substituted chalcones in a two-step process. First, propargylic alcohols were obtained by addition of ethoxyacetylene anion to aromatic ketones. Activation of the propargylic alcohols using a catalytic amount
