Abstract o-Isopropenyl phenoxyactic acids 1 and 8 on treatment with thionyl chloride followed by aqueous workup furnished the acylated products 4 and 9 in moderate yields. The corresponding acid chlorides could also be cyclised with stannic chloride. The acid chlorides from 10 and 11 however did not undergo cyclisation.
