A direct transformation of ortho-alkynylated aromatic vinyl ethers to 1-iodonaphthalenes and other iodo-heterocycles under mild Lewis acidic conditions in the presence of iodide as an external nucleophile is reported. The first example of an iodoannulation strategy using a nucleophilic source of iodine, coupled with good to excellent yields, exclusive alpha regioselectivity and a broad substrate scope makes this work an attractive avenue towards the construction of aromatic iodides.

Paragraph 0017; 0024-0025, (2018/04/01)
The invention relates to a preparation method of Agomelatine. The preparation method is characterized by comprising the following steps: halogenating 7-methoxy-naphthylamine, performing potassium vinyltrifluoroborate substituting and ammonifying and protecting acetyl, so as to obtain a product. The preparation method has the advantages of being easily available in raw materials, concise in processes, high in total yield, less in by-products and simple in aftertreatment, therefore, the preparation method is suitable for industrial production.

Agomelatine was synthesized from 8-aminonaphthalen-2-ol by diazotization-iodination, formylation, C-C bond formation by nitroaldol and Pd/C hydrogenation of β-nitrovinylnaphthalene followed by N-acetylation. The route reported employs readily and commercially viable starting materials and reagents, and can potentially be utilized for process synthesis of agomelatine.
