Kristallstruktur eines 2-Dimethylamino-3,3-dimethyl-4(3H)-pyridons
CHIMIA, 1982 3-Dimethylamino-2,2-dimethyl-2H-azirine (1) reacts with alkyl phenyl substituted cyclopropenones 2 in benzene at 130 °C to give a mixture of the two isomeric 4(3H)-pyridones 3 and 4, resulting from a nucleophilic attack at C(2) and C(1) of the ...

Acremolin, a stable natural product with an antiaromatic 1H-azirine moiety? A structural reorientation [PDF]
, 2012 Recently, acremolin (4), a novel modified base, was isolated from a marine-derived fungus and claimed to possess a structure with a 1H-azirine moiety. It is shown now that the reported NMR data are not compatible with this antiaromatic heterocycle, which
