摘要

The cyclization of 2-naphthylmethylpent-4-en-1-oic acids by protonic acids yields tetrahydrophenanthrenecarboxylic acids. A new and convenient method of synthesizing polymethylanthracenes and-phenanthrenes has been developed. Some aspects of these cyclizations are also discussed. A detailed analysis of the NMR spectra of these anthracenes and phenanthrenes confirms the assignments.
