, p. 826 - 844 (2019)
Various types of terminal acetylenic iminium triflates (propyne iminium salts) featuring a ketiminium or an aldimin-ium group have been prepared for the first time by protiodesil-ylation of the corresponding trimethylsilyl-substituted acetylenic iminium s

Paragraph 0011-0012, (2020/10/05)
The invention discloses a method. βAryl. αA synthetic method of a naphthol compound, which is synthesized in one step with a simple and easily available deoxybenzoin compound and an alkyne compound as a raw material. βAryl. αNaphthol-based compounds. The method provided by the invention realizes the simple and efficient preparation of the aromatic ring through domino dehydrogenation cyclization. βAryl. αCompared with a traditional synthetic method, the naphthol compound has the advantages of cheap raw materials, simple operation, environmental friendliness, high yield, wider substrate accommodation range, complete regioselectivity and high atom utilization rate.

scheme or table, p. 585 - 588 (2012/02/01)
Substituted 1-acyl-1-indanols were prepared using the corresponding readily commercially available substituted indanones as starting materials. Treatment of each 1-acyl-1-indanol derivative with sodium methoxide in hot methanol furnished a regiospecific 2-hydroxy-α-tetralone derivative, which was an α-keto rearrangement product. Each substituted 2-hydroxy-α-tetralone then underwent dehydration to afford the corresponding 1-naphthol derivative.
