Safety of 2,5-Dimethoxybenzaldehyde. In 2019.0 HETEROCYCLES published article about NAZAROV CYCLIZATION; DERIVATIVES; ACYLATION; ANALOGS in [Tsukamoto, Hirokazu; Nomura, Yumi; Doi, Takayuki] Tohoku Univ, Grad Sch Pharmaceut Sci, Aoba Ku, 6-3 Aza Aoba, Sendai, Miyagi 9808578, Japan in 2019.0, Cited 50.0. The Name is 2,5-Dimethoxybenzaldehyde. Through research, I have a further understanding and discovery of 93-02-7.
Synthetic studies on palmarumycin C-6 with a naphthyl acetal at the C-3 position in 4,7-dihydroxy-1-indanone as a lower homologue of spirobisnaphthalenes are described herein. We investigated three approaches: 1) Nazarov cyclization of benzoylketene acetal, 2) intramolecular Friedel-Crafts acylation of naphtho[1,8-de]-1,3-dioxin-2-aryl-2-acetic acid chloride, and 3) double oxa-Michael addition of 1,8-dihydroxynaphthalene to 3-bromo-l-indenone. The last approach successfully afforded the natural product after the removal of acetates that serve as protecting groups for phenolic hydroxyls under acidic conditions.
