Rational Synthesis of Tripyrranes Michał Gałeęzowski Jarosław Jaźwiński Jan P. Lewtak Daniel T. Gryko 10.1021/jo900602z.s001 https://acs.figshare.com/articles/journal_contribution/Rational_Synthesis_of_Tripyrranes/2837044 The rational, chromatography-free synthesis of two regioisomeric 5,10-diaryltripyrranes from pyrrole and aromatic acids has been developed. The strategy is general and should be applicable to a broad range of acids. This methodology was successfully applied to the synthesis of monoprotected dipyrrane. The oxidation of <i>N</i>,<i>N</i>′-bis-mesyltripyrrane under basic conditions led to the formation of both known tripyrrin-1-one and unknown 1-methoxytripyrrina fluorescent dye strongly absorbing green light. 2009-08-07 00:00:00 pyrrole acid synthesis methoxytripyrrin strategy oxidation methodology TripyrranesThe diaryltripyrrane monoprotected dipyrrane formation Rational Synthesis dye regioisomeric tripyrrin
