5,17-Diformyl-25,26,27,28-tetra­propoxy­calix[4]arene

The title compound, C(42)H(48)O(6), was obtained via formyl­ation of 25,26,27,28-tetra­propoxycalix[4]arene with dichloro­methyl methyl ether and tin tetra­chloride. It adopts a pinched cone conformation, which leads to an open cavity. The two opposite aromatic rings bearing formyl groups are almost...

Sumario:The title compound, C(42)H(48)O(6), was obtained via formyl­ation of 25,26,27,28-tetra­propoxycalix[4]arene with dichloro­methyl methyl ether and tin tetra­chloride. It adopts a pinched cone conformation, which leads to an open cavity. The two opposite aromatic rings bearing formyl groups are almost parallel, making a dihedral angle of 29.1 (2)°. The other pair of opposite rings are close to being perpendicular, making a dihedral angle of 73.6 (1)°. Adjacent rings are almost perpendicular, making dihedral angles of 78.8 (2), 81.6 (1), 78.2 (1) and 74.7 (1)°.
