In the mol-ecule of the title compound, C(29)H(40)O(6), the carbon atom belonging to the propyl chain is connected to two aromatic rings that open up the C(ar-yl)-C-C(ar-yl) angle to 111.5 (1)°. The four-atom -O-CH(2)-C(=O)-O- linkage between the aromatic ring and the tert-butyl group assumes a (-)anti-periplanar conformation for one substituent and a (-)syn-periplanar conformation for the other substituent; the O-C-C-O torsion angles are -173.7 (2) and -10.2 (3)°.
在标题化合物C(29)H(40)O(6)的分子中,属于丙基链的碳原子与两个芳香环相连,使C(芳基)-C-C(芳基)角扩大到111.5 (1)°。芳香环与叔丁基之间的四原子-O-CH(2)-C(=O)-O-键,一个取代基呈(-)反式-平面构象,另一个取代基呈(-)顺式-平面构象;O-C-C-O扭转角分别为-173.7 (2)°和-10.2 (3)°。
