| titleOfInvention | Production of 3-propenylpropiophenone |
| abstract | PURPOSE: To easily obtain in high yield the titled substance useful as an intermediate for synthesizing flavoxate hydrochloride, a remedy for pollakiuria, by subjecting a 3-allylpropiophenone to a rearrangement reaction in the presence of a salt of Rh or Pd or its complex. n CONSTITUTION: A compound shown by the formula I (R is H or R'CO; R' is lower alkyl) is subjected to a rearrangement reaction in the presence of a salt (e.g., halide, sulfate or acetylacetonato) of Rh or Pd or its complex (e.g., carbonyl complex or phosphine complex) in a solvent such as alcohol, carboxylic acid, etc., at room temperature 100°C for 0.5W35hr to give a compound shown by the formula II. A compound shown by the formula II wherein R is H is not isolated and can be directly and continuously acylated or a compound shown by the formula I wherein R is H is acylated and can be directly subjected to a rearrangement reaction to give the compound shown by the formula II. n EFFECT: The reaction can be advanced with a small amount of catalyst under mild condition. n COPYRIGHT: (C)1987,JPO&Japio |
