Gluconic acid aqueous solution

Quite recently, Gu and coworkers reported the use of gluconic acid aqueous solutions ( GAAS ) as medium for Michael addition of indoles to ot,p-unsaturated ketones (Scheme 10). Compared with other traditional aqueous or organic solvents, gluconic acid has been found to greatly promote the reaction rate of Michael addition, as shown in... [Pg.63]

Zhang and coworkers used gluconic acid aqueous solution (GAAS) in the strategy to obtain tetrasubstituted pyrroles, which were obtained in high yields (up to 93%) [111]. Functional groups are well tolerated in this process (40 examples), the green media can be reused, and it is completely inexpensive and environmentally friendly. [Pg.230]

Colourless crystals m.p. I25°C, soluble in water and alcohol. In aqueous solution forms equilibrium with its lactones. Gluconic acid is made by the oxidation of glucose by halogens, by electrolysis, by various moulds or by bacteria of the Acetobacter groups. [Pg.190]

In presence of the enzyme glucose oxidase, an aqueous solution of glucose undergoes oxidation to gluconic acid with formation of hydrogen peroxide which can be determined by anodic oxidation at a fixed potential. [Pg.639]
