چکیده
In the title compound, C(20)H(20)N(2), the quinoxaline ring adopts a very distorted half-chair conformation [N=C-C=N = 22.7 (2)° for the nominally coplanar atoms] and the cyclo-hexane ring adopts a chair conformation. The quinoxaline and cyclo-hexane rings are cis-fused. The two phenyl rings form a dihedral angle of 63.88 (7)°.

The structure of the title racemic compound, C(20)H(20)N(2), shows close similarity to that of the enanti-omerically pure (4aR,8aR)-2,3-diphenyl-4a,5,6,7,8,8a-hexa-hydro-quinoxaline [Wang & Ye (2008 ▶). Acta Cryst. E64, o359-o359]. The similarity applies to the unit-cell parameters as well as to the packing of the constituent mol-ecules. Similar packing is conditioned by a lack of directed inte...

The title mol-ecule, C(20)H(20)N(2), is chiral; the absolute configuration follows from the known chirality of the input reagents. In addition to van der Waals forces, C-H⋯π ring inter-actions are also present. The angle between the planes of the phenyl rings is 65.6 (1)°. The heterocyclic ring of the quinoxaline system has a twist-boat configuration, while the cyclohexane ring has a chair conf...

A new member of the gymnodimine class of spiroimine toxins has been isolated from a laboratory culture strain of Alexandrium ostenfeldii. Extensive one-dimensional (1D) and two-dimensional (2D) NMR data analysis was used to elucidate its structure as 12-methylgymnodimine B.

The hemisynthesis of the title compound, C22H32O2, was carried out through direct acetyl-ation reaction of the naturally occurring diterpene totarol [systematic name: (4bS,8aS)-4b,8,8-trimethyl-1-propan-2-yl-5,6,7,8a,9,10-hexa-hydro-phen-an-thren-2-ol]. The mol-ecule is built up from three fused six membered rings, one saturated and two unsaturated. The central unsaturated ring has a half-chair...

In the title compound, C(28)H(27)NO(2), the oxazinone ring adopts a twist-boat conformation and the cyclo-hexene ring has a twisted envelope conformation. The crystal structure is stabilized by weak non-classical inter-molecular C-H⋯O hydrogen bonds.
