چکیده
In the crystal structure of the title compound, C(22)H(25)NO(4), inter-molecular O-H⋯O hydrogen bonds involving the hy-droxy group of the 4-(amimometh-yl)phenol fragment and the C=O group connect the mol-ecules into infinite chains along the c axis. Two C atoms of the propyne group are disordered over two sites with occupancy factors of 0.53 (2) and 0.47 (2).

In the title compound, C(19)H(22)N(2)O(4), the dihedral angle between the aromatic rings is 67.33 (2)°. In the crystal, mol-ecules are linked through N-H⋯O and O-H⋯O hydrogen bonds, generating a two-dimensional network lying parallel to (100). As a result of the twist of the mol-ecular skeleton and the hindrance of the tert-butyl groups, no π-π inter-actions exist between the aromatic rings.

The title compound, C(25)H(44)N(4)O(5), exhibits a turn with the main chain reversing direction, held together by an intramolecular N-H.O hydrogen bond. In the urea fragment, a notable amide C-N bond between the carboxyl C and the tertiary N atom shows marked single-bond character [1.437 (2) A]. The dihedral angle of the beta-alanyl residue, centrally located in the turn, is gauche [69.2 (2) de...
