A novel and one‐pot domino reaction of propargylamines with benzoylacetonitriles and β‐keto esters for the regiospecific synthesis of polysubstituted furans and furo[3,4‐c]coumarins has been developed. The reaction is believed to proceed by sequential 1,4‐conjugate addition of benzoylacetonitriles/β‐keto esters to propargylamines, 5‐exo‐dig annulation/isomerization to form the fully substituted furans,...
A one-pot domino reaction involving Lewis acid-mediated nucleophilic-substitution/intramolecular-cyclization/reverse Claisen condensation of 2-(aryl(piperidin-1-yl)methyl)phenols and 1,3-diketones has been developed for the synthesis of 2-(3-oxo-1-phenylbutyl)phenyl acetates in good to excellent yields (77%–95%). The construction of the products has been accomplished via the domino generation of two...
