Abstract
Novel 3-substituted derivatives of 2,2-dimethyl-5-substituted phenoxy-pentanoic acids of general formula (I) are prepared. These compounds are prepared from 2,2-dimethyl-5-substituted phenoxy-3-hydroxy-pentanoic acid-(beta)-lactones(general formula (II)). Methods of preparing the novel (beta)-lactones by condensing relevant phenoxypropanals with dimethylketene are disclosed.
