observed during a Friedel–Crafts acylation/demethylation cascade. In contrast to this cascade, oxygen-containing acylating reagents do not undergo the demethylation step. By the methodology elaborated here, an access is provided to important intermediates for the total synthesis of seminaphthorhodafluor (SNARF) dyes. High selectivity is observed during a Friedel–Crafts acylation/demethylation cascade
摘要 在Friedel-Crafts酰化/去甲基化级联反应中观察到高选择性。与该级联反应相反,含氧的酰化剂不进行脱甲基步骤。通过此处阐述的方法,可以为重要的中间体提供全萘四氟(SNARF)染料的全合成。 在Friedel-Crafts酰化/去甲基化级联反应中观察到高选择性。与该级联反应相反,含氧的酰化剂不进行脱甲基步骤。通过此处阐述的方法,可以为重要的中间体提供全萘四氟(SNARF)染料的全合成。
