CCDC no.: 1500923The asymmetric unit of the tilte crystal structure is shown in the gure. Tables 1 and 2 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters.
Source of materialThe mixture of 2,2-bis(hydroxymethyl)butyric acid (1.92 g, 13 mmol), 2-bromobenzaldehyde (2.21 g, 12 mmol), cyclohexane (15 mL), N,N-dimethylformamide (5 mL) and p-toluene sulfonic acid (0.13 g, 0.75 mmol) were re uxed with stirring for 5 h. After the mixture was cooled, sodium bicarbonate (0.06 g, 0.76 mmol) was added to neutralize the mixture and stirred at room temperature for 1 h. The solvent was evaporated under reduced pressure and then ethyl acetate was
