Source of material
Trimethylolpropane (1.47 g, 11 mmol), 4-methoxybenzalde-hyde (1.36 g, 10 mmol), cyclohexane (10.0 mL), N,N-dimethytformamide (5.0 mL) and p-toluene sulfonic acid (0.15 g) were heated and stirred at 388 K for 5 h. Now sodium bicarbonate (0.09 g) was added to dissolve the residue after the solvent was evaporated. The solution was washed with brine (10 mL*3), and dried with anhydrous sodium sulfate. The resulting solution was filtered and evaporated, and the product was recrystallized from cyclohexane and ethyl acetate to afford colourless crystals (1.89 g, yield 75%).
Experimental details
All hydrogen atoms were positioned geometrically. The Uiso values of the hydrogen atoms of methyl groups were set to 1.5 Ueq(C) and the Uiso values of all other hydrogen atoms were set to 1.2 Ueq(C).
Comment
Acetal compounds were widely used in fragrances and food flavors [1], [2], [3]. Acetal compounds are stable in neutral and alkaline conditions and will degradate and generate a material of small molecules in acidic conditions. Polyfunctional branched compounds is a new class of compounds with a wide range of applications [4], [5], [6], [7]. Herein, an acetal compound is reported, which was synthesized and characterized by single-crystal X-ray diffraction [8], [9].
In the structure, the torsion angles of C(9)—O(2)—C(8)—O(3), C(11)—O(3)—C(8)—O(2) and C(8)—O(3)—C(11)—C(10) are 63.56(16), −63.37(16) and 58.19(16), respectively, indicating that the 1,3-dioxane ring exhibits a chair conformation. The torsion angle of C(11)—O(3)—C(8)—C(5) is 174.60(12), suggesting that the phenyl ring occupies the equatorial bond of C(8) atom. The geometry of the two crystallographically independent molecules are very similar.
