Synthesis of an alkylthio-substituted dibenz[a,j]anthracene with improved solubility via the oxidative photocyclization of 1,3-distyrylbenzene derivatives

, p. 1904 - 1911 (2013/04/10)
A series of 1,3-distyrylbenzene compounds bearing different substituents at the 2-position have been synthesized and subjected to an oxidative photocyclization process. The 1,3-distyrylbenzene compounds substituted with chloro, alkylthio, and diphenylphosphino groups at the 2-position afforded dibenz[a,j]anthracene derivatives, whereas those bearing methyl, trimethylsilyl, dimethylamino, butoxy, and fluoro groups gave benzo[c]chrysene derivatives. The solubility of dibenz[a,j]anthracene in organic solvents was improved by the introduction of alkylthio groups.
The synthesis of trianglimines: On the scope and limitations of the [3 + 3] cyclocondensation reaction between (1R,2R)-diaminocyclohexane and aromatic dicarboxaldehydes

, p. 1157 - 1170 (2007/10/03)
The synthesis of aromatic dicarboxaldehydes, using dilithiation methodology is described along with their reactivity, in the [3 + 3] cyclocondensation reaction, with (1R,2R)-diaminocyclohexane to give trianglimine macrocycles. The scope and limitations of the cyclocondensation reaction are studied and some comments on the properties of the novel macrocycles are made such as their conformation in solution and temperature dependent dynamic NMR behaviour.
Vilsmeier Reaction on Some Alkyl-1,4-cyclohexadienes
Raju, B.,Rao, G. S. Krishna
, p. 892 - 893 (2007/10/02)
Vilsmeier reaction on five alkyl-1,4-cyclohexadienes (I-V) has been studied.The structures of the resulting benzenedi- and tricarboxaldehydes (VII-XIII) have been assigned on spectral and elemental analyses data.
