118-71-8, Name is 3-Hydroxy-2-methyl-4-pyrone, molecular formula is C6H6O3, belongs to indole-building-block compound, is a common compound. In a patnet, author is Egami, Hiromichi, once mentioned the new application about 118-71-8, Quality Control of 3-Hydroxy-2-methyl-4-pyrone.
Asymmetric dearomatizing fluorocyclization of indole derivatives was investigated using a dicarboxylate phase-transfer catalyst. This reaction proceeds under mild reaction conditions to provide fluoropyrroloindoline derivatives in a highly enantioselective manner. Various substitution patterns on the indole ring are well tolerated. To facilitate the reaction and ensure reproducibility, the addition of water is essential, and its possible role is discussed.
