Photochemical dehydrogenation of 3,4-dihydro-2-pyridones.
نویسندگان
چکیده
Photochemical dehydrogenation of various substituted 3,4-dihydro-2-pyridones was achieved in a very efficient way by employing 10-15 mol% of photo-induced electron transfer sensitizers like 9-cyanoanthracene, 9-cyanophenanthrene and 1-cyanonaphthalene in presence of molecular oxygen, for the first time.

Light-induced stereospecific intramolecular [2+2]-cycloaddition of atropisomeric 3,4-dihydro-2-pyridones.
Atropisomeric 3,4-dihydro-2-pyridones undergo stereospecific [2+2]-photocycloaddition in solution with high stereoselectivity (ee > 98% and de > 96%) in the product. The chiral transfer during phototransformation was rationalized based on the stability/reactivity of the biradical.

A green approach for the synthesis of a set of ten 4-aryl substituted-5-alcoxy carbonyl-6-methyl-3,4-dihydro-2(1H)-pyridones using Meldrum's acid has been devised, the absence of solvent and the activation with infrared irradiation in addition to a multicomponent protocol are the main reaction conditions. The transformations proceeded with moderated yields (50-75%) with a reasonable reaction ra...

Fluorescence quantum yields, singlet lifetimes and triplet yields for 2-methyl-2,3-dihydro4(1 H)-quinolinone and N-methyl-2,3-dihydro-4(l H)-quinolinone were determined as a func tion o f temperature. In non-polar solvents, an efficient non-radiative process identified as an indirect singlet —*• triplet transition occurring through S2(n,jr*) was found to depopulate the lowest S 1(7t,7E*) state...

Aldehyde phenyl hydrazones 2a-i undergo oxidative dehydrogenation with Chloramine-T to give nitrile imines, which are trapped in situ by ethyl oleate 1 to afford 8-(5-Aryl-4-octyl-2-phenyl-3,4-dihydro-2Hpyrazol-3-yl)-octanoic acid ethyl esters 3a-i in good yield. The structures of the cycloadducts were confirmed by spectral studies and elemental analysis.
