The reaction is most notably used in the synthesis of It involves an additional dehydration under the same conditions as the cyclization, giving an isoquinoline. PomeranzFritsch reaction; References Edit August Bischler, Mechanism, references and reaction samples of the PomeranzFritsch Isoquinoline Synthesis The PomeranzFritsch reaction, also named PomeranzFritsch cyclization, is a name reaction in the organic chemistry.
It is named after Paul Fritsch ( ) and Csar Pomeranz ( ). In general it is a synthesis of isoquinoline. PomeranzFritsch Synthesis of Isoquinoline: GasPhase Collisional Activation Opens Additional Reaction Pathways Shibdas Banerjee, #, Pomeranz Fritsch Synthesis of Isoquinoline: GasPhase Collisional Activation Opens Additional Reaction Pathways Abstract: We have investigated the gasphase production of isoquinoline by performing collisional activation on benzalaminoacetal, the first intermediate in the classic solutionphase PomeranzFritsch synthesis of isoquinoline.
We have elucidated the reaction Acidcatalyzed cyclization of benzalaminoacetal results in the formation of the isoquinoline nucleus. This reaction, first reported by Pomeranz and Fritsch, has been used in the synthesis of a variety of isoquinoline compounds. The process is carried out in two stages. In step one, a condensation leads to the benzalaminacetal. A new modification of the pomeranzfritsch isoquinoline synthesis.
