Gayone, Esteban Ascolani, Hugo Wurst, Klaus Lingenfelder, Magalí Kellogg, Richard M. 5-amino [6] hexaheliceno STM UHV Research Subject Categories::NATURAL SCIENCES::Chemistry Cromatolografía Artículo A convergent synthesis of racemic 5-amino[6]hexahelicene is described. Cross-coupling reactions are used to assemble a pentacyclic framework, and a metal-catalyzed ring-closure comprises the final step. The enantiomers were separated by means of chromatography and the absolute configurations were assigned by comparison of the CD spectra with hexahelicene. The t1/2 value for racemization at 210 8C was approximately 1 hour. Scanning tunneling microscopy (STM) measurements were carried out on enantiopure and racemic samples of aminohelicene on Au(111) under ultrahigh vacuum (UHV) conditions. 2018-07-31T16:40:45Z 2018-07-31T16:40:45Z 2016 info:eu-repo/semantics/article https://onlinelibrary.wiley.com/doi/pdf/10.1002/chem.201502798 Van der Meijden, M., Gelens, E., Murillo-Quirós, N., Fuhr, J., Gayone, E., Ascolani, H., Wurst, K., Lingenfelder, M., & Kellogg, R.
