PROCESS FOR 5-AROYLATION OF 1,2-DIHYDRO-3H-PYRROLO(1,2-A)PYRROLE-1-CARBOXYLIC ESTERS

PROCESS FOR 5-AROYLATION OF 1,2-DIHYDRO-3H-PYRROLO(1,2-A)PYRROLE-1-CARBOXYLIC ESTERS

A process for 5-aroylation of 1,2-dihydro-3H-pyrrolo [1,2-a]pyrrole-1-carboxylic esters and nitriles by reacting a pyrrolo pyrrole with an aroyl morpholide and an inorganic acid chloride in an inert aprotic solvent; followed by treatment with weak or strong base to form: The nitrile (V) can be hydro...

Zusammenfassung:A process for 5-aroylation of 1,2-dihydro-3H-pyrrolo [1,2-a]pyrrole-1-carboxylic esters and nitriles by reacting a pyrrolo pyrrole with an aroyl morpholide and an inorganic acid chloride in an inert aprotic solvent; followed by treatment with weak or strong base to form: The nitrile (V) can be hydrolyzed to the acid (III).
