A convenient synthesis of a 2,7-difunctional tetra(alkoxy)triphenylene involving 4,4′- diacetoxy-3,3′-dialkoxybiphenyl as a key precursor and its conversion to extended hybrid mesogenic compounds
(Taylor & Francis Ltd, 2013-06-03)
A new rational pathway to 2,7-difunctionalised-β-hexa-substituted triphenylenes is presented, requiring less protection/deprotection and purification steps than more conventional synthetic procedures in the framework of ...
An Improved stereospecific synthesis of (Z,E)-tetradecadienal. Sex pheromone component of Stenoma cecropia
(1998)
(Z,E)-9, 11-Tetradecadienal, a sex pheromone component of Stenoma cecropia, has been synthesized in 7 steps and 61% overall yield. The synthesis utilized a palladium catalyzed coupling between 9-decynyl tert-butyldinethylsilyl ...
