A new synthetic route of 1,1-Bis(4-methoxyphenyl)prop-2-yn-1-ol

At the same time, in my other blogs, there are other synthetic methods of this type of compound,101597-25-5, 1,1-Bis(4-methoxyphenyl)prop-2-yn-1-ol, and friends who are interested can also refer to it.

Adding a certain compound to certain chemical reactions, such as: 101597-25-5, 1,1-Bis(4-methoxyphenyl)prop-2-yn-1-ol, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, HPLC of Formula: C17H16O3, blongs to alcohols-buliding-blocks compound. HPLC of Formula: C17H16O3

Example 1 [0193] 1.20 g (2.0 mmol) of a naphthol compound represented by the following formula (22) and 0.80 g (3.0 mmol) of a propargyl alcohol compound represented by the following formula (23) were dissolved in 70 ml of toluene, 0.022 g of p-toluenesulfonic acid was further added to the resulting solution, and the obtained mixture was stirred under reflux by heating for 1 hour. After a reaction, the solvent was removed, and the obtained product was purified on silica gel by chromatography to obtain 1.35 g of a white powder product. The yield was 80 %. [0194] The elemental analysis values of this product were 78.22% of C, 6.72 % of H, 1.55 % of N and 3.75 % of S which were almost equal to the calculated values of C52H52O6 (C: 78.26 %, H: 6.81 %, N: 1.66 %, O: 9.48 %, S: 3.80 %) [0195] When the proton nuclear magnetic resonance spectrum of the product was measured, it showed 18H peaks based on the methyl proton and methylene proton of a tetramethyl-cyclohexane ring at delta of around 1.0 to 3.0 ppm, 20H peaks based on the methyl proton of a methoxy group, the methyl proton of a methylthio group and the ethylene proton of a morpholino group at delta of around 2.3 to 5.0 ppm and 19H peaks based on an aromatic proton and an alkene proton at delta of around 5.6 to 9.0 ppm. Further, when the 13C-nuclear magnetic resonance spectrum was measured, it showed a peak based on the carbon of an aromatic ring at delta of around 110 to 160 ppm, a peak based on the carbon of an alkene at delta of around 80 to 140 ppm and a peak based on the carbon of an alkyl at delta of around 20 to 60 ppm. [0196] It was confirmed from the above results that the isolated product was a compound represented by the following formula (24).
