Abstract:
In the title mol-ecule, C(22)H(15)NO(3), the configuration about the ethyl-enic double bond is Z configuration and it is approximately coplanar with the adjacent phenyl ring and benzoxazole ring system as indicated by the C(H)=C(O)-C(phen-yl)-C(phen-yl) and O(benzoxazole)-C-C(H)=C(O) torsion angles of 179.88 (15) and 5.7 (2)°, respectively. The dihedral angle between the essentially planar (r.m.s. deviation = 0.080 Å) 2-(1,3-benzoxazol-2-yl)-1-phenyl-ethenyl group and the benzoate phenyl ring is 61.51 (6)°. A short intra-molecular O⋯O non-bonded inter-action of 2.651 (2) Å is present.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
