چکیده

A facile and moderately functional-group-tolerant synthetic method for the preparation of 7,8-diaza[5]helicenes has been developed. It comprises of an oxidative ring-closing process of 1,1'-binaphthalene-2,2'-diamine (BINAM) derivatives with a chlorine-containing oxidant (t-BuOCl) in the presence of a base (2,6-lutidine). In addition the basic physicochemical properties of newly synthesized compounds have been investigated.

The title compound, C(44)H(30)N(4)O(2), was prepared from 6,6'-dibromo-2,2'-dieth-oxy-1,1'-binaphthalene through a coupling reaction with 4-(4,4,5,5-tetra-methyl-1,3,2-dioxaborolan-2-yl)benzaldehyde followed by a Knoevenagel reaction with malononitrile. The dihedral angle between the symmetry-related naphthalene ring systems is 68.82 (8)° while the dihedral angle between the the naphthalene rin...

The title compound, C(34)H(22)Cl(4)N(4)O(2)·2CHCl(3), is a new urea based on the 1,1'-binaphthalene skeleton, which crystallizes with two mol-ecules of binaphthalene and four mol-ecules of chloro-form in the unit cell. The chloro-form solvent mol-ecules do not participate in non-covalent inter-actions and therefore, can be found in several positions. The binaphthalene mol-ecules are connected v...

An Efficient Synthesis of Functionalized Helicenes

[5]and [6]helicenebisquinones can be prepared easily and in quantity by combining enol ethers of 1,4diacetylbenzene or 2,7-diacetylnaphthalene with p-benzoquinone. Similar diethenyl aromatics that either have no ether functions or have them attached not to the double bonds, but to the aromatic rings, give the corresponding helicenes in only low yields and low purities. [6]Helicenebisquinone 11c...
