Directed Metallations of 4-Ethylidenetetronic Acid O-Methyl Ether and its Derivatives as a Synthetic Entry to Natural 4-Oxyfuran-2-ones

Lithium di-isopropylamide removes the C-2(α-)-protons from the O-methyl tetronates (11) and (20) in a regioselective manner leading to the corresponding novel anions e.g. (18).The vinyl anions then react with a range of electrophiles providing a preparati
