A microorganism capable of degrading homophthalic acid as a sole carbon source was isolated from garden soil. The strain was identified as Pseudomonas alcaligenes. The organism degraded homophthalate by a pathway which involved phenylacetate and p-hydroxyphenylacetate as intermediates. The intermediates

A microwave-assisted, environmentally friendly, high-yielding, time-saving synthesis of medicinally important 3-substituted isocoumarins was carried out in a single step by direct condensation of homophthalic acid with aryol and acyl chlorides under solvent-free conditions without any solid support. The synthesised isocoumarins
