Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 101597-25-5, name is 1,1-Bis(4-methoxyphenyl)prop-2-yn-1-ol. A new synthetic method of this compound is introduced below., Recommanded Product: 101597-25-5
10244] A propargyl alcohol compound represented by thefollowing formula was provided. 10245] 1.55 Grams (4.0 mmols) of the indenonaphthol compound obtained in Example 4 and 1.40 g (5.2 mmols) of the above propargyl alcohol compound were dissolved in 47 ml of toluene and to which was, further, added 0.03 g of camphorsulfonic acid to conduct the reaction at 100 C. for one hour.10246] After the reaction, the solvent was removed, the reaction product was refined by chromatography (solvent chloroform) using silica gel and was, thrther, recrystallized with acetonitrile to obtain 1.86 g (2.9 mmols) of a white solid material of an indenonaphthopyran represented by the following formula (ES). The yield was 73%.
