A naturally occurring isoquinolinone alkaloid marinamide and its methyl ester were synthesised from phthalic anhydride over eight steps in 46% and 52% overall yield. The key intermediate methyl 2-(1-benzyl-1H-pyrrole-2-carbonyl) benzoate was synthesised from the acid chloride of mono methyl phthalate and 1-benzyl-1H-pyrrole catalysed by Zinc oxide under solvent-free conditions at room temperature.
