Facile synthesis and characterization of new photochromic trans-dithienylethenes functionalized with pyridines and fluorenes.
Three symmetrical and unsymmetrical trans-dithienylethenes functionalized with pyridines and fluorenes have been synthesized by a facile one-pot procedure, and their characteristics and photochromism were investigated. Their fluorescent intensity was efficiently regulated by a photochromic switch using alternative irradiation with UV light and visible light. Moreover, by protonation and complex...
متن کاملOne-pot synthesis of highly functionalized pyridines via a rhodium carbenoid induced ring expansion of isoxazoles.
A concise one-pot synthesis of highly functionalized pyridines has been developed. The first step in the reaction sequence is the formal insertion of rhodium vinylcarbenoids across the N-O bond of isoxazoles. Upon heating, the insertion products undergo a rearrangement to give 1,4-dihydropyridines. DDQ oxidation then affords the corresponding pyridines in 31-84% yield. The process has proven ge...
متن کاملIsothiourea-Mediated One-Pot Synthesis of Functionalized Pyridines**
Acids to bases: The synthesis of 2,4,6-trisubstituted pyridines from (phenylthio)acetic acid and a range of α,β-unsaturated ketimines is reported. This process proceeds by intermolecular Michael addition/lactamization, thiophenol elimination, and N- to O-sulfonyl migration, giving 2-sulfonate-substituted pyridines which are readily derivatized to generate structural diversity.
متن کامل4-Aryl-2, 6-di(pyren-1-yl)pyridines: A facile procedure for synthesis and studying of fluorescence properties
Pyrene and its derivatives exhibit thermal stability, high extinction coefficients, excimer formation, high photoluminescence, long fluorescence lifetime, fluorophoric properties and enhanced charge carrier mobility which make them find applications in optoelectronic area and are useful as large planar synthetic building blocks in supramolecular chemistry. One of the approaches to overcome this...
متن کاملA facile one-pot synthesis of tetrahydrodibenzo[a,i]phenanthridines and novel hexahydrodicyclopenta[b,d]pyridines
A series of eight 5-aryl/heteryl-7,8,13,14-tetrahydrodibenzo[a,i]phenanthridines, another series of seven novel 5aryl/heteryl-1,2,3,6,7,8-hexahydrodicyclopenta[b,d]pyridines and two hitherto unknown bridged 2,4-diaryl-3azabicyclo[3.2.1]octan-8-ones have been synthesised by the condensation of α-tetralone and various aryl/heteryl aldehydes, cyclopentanone and same aryl/heteryl aldehydes and cycl...
