One approach would be to use the SMILES string 'C[Pb](*C)(C)C' and remove substances containing 'c[Pb]' (lowercase specifies aromatic). There are technical challenges since PubChem doesn't seem to provide an option to distinguish between aromatic and aliphatic carbons. For more information on SMILES, see https://en.wikipedia.org/wiki/Simplified_molecular-input_line-entry_system.

Terephthalates whose toxicology studies we have reviewed to date don't share the hazards that are common to studied orthophthalates. This is thought to be due to the fact that terephthalates are unlikely to break down to a toxic monoester. Orthophthalates are capable of breaking down to a toxic monoester.
