Processes for preparing 2-substituted propionic acid and derivatives thereof |
| abstract |
There are disclosed a process for preparing 2-hydroxy-2-(6-methoxy-2-naphthyl)propionic acid or 2-hydroxy-(4-substituted phenyl)propionic acid derivative which comprises reacting 2-methoxynaphthalene or substituted benzene derivatives with pyruvic acid in the presence of a Lewis acid and then, if necessary, hydrolyzing the obtained product, and a process for preparing 2-(6-methoxy-2-naphthyl)propionic acid or 2-(4-substituted phenyl)propionic acid derivative which comprises reducing 2-hydroxy-2-(6-methoxy-2-naphthyl)propionic acid or 2-hydroxy-2-(4-substituted phenyl)propionic acid derivative in a lower aliphatic acid in the presence of an inorganic acid under hydrogen atmosphere by using a metal catalyst. |
