概要

• 論文の詳細を見る

• The synthesis of 2,9-dimethoxybenzofuro-[2,3-<I>b</I>]benzofuran from its 5a,10b-dihydro-compound was carried out by bromination with <I>N</I>-bromosuccinimide, followed by dehydrobromination. The attempted preparation of 2,9-dimethyl-, 2,9-dichloro-, and 2,4,7,9-tetrachloro-derivatives was unsuccessful.
