Camps quinoline synthesis

- Dec 03, 2018-

The Camps quinoline synthesis (also known as the Camps cyclization) is a chemical reaction whereby an o-acylaminoacetophenone is transformed into two different hydroxyquinolines (products A and B) using hydroxide ion.[1][2][3][4]

The relative proportions of the hydroxyquinolines (A and B) produced are dependent upon the reaction conditions and structure of the starting material. Although the reaction product is commonly depicted as a quinoline (the enol form), it is believed that the keto form predominates in both the solid state and in solution, making the compound a quinolone.[5]

An example of the Camps reaction is given below:[5]
