Abstract
The title compound, C20H21NO3, is a derivative of Aib (α-aminoisobutyric acid) and is cyclized at the Cα position by bi-phenyl rings. The seven-membered ring possesses C2 symmetry. The Cα cyclization causes the backbone to assume a helical conformation in the crystal structure. The packing of the mol-ecules is stabilized by intermolecular C-H···O, C-H···π and N-H···O hydrogen bonds.
