Unusual formation and X-ray crystal structure of stable anti-Bredt compounds by reaction of 3a,6a-diazapentalenes with dimethyl acetylenedicarboxylate

Abstract

The reaction of 1-aroyl-2-aryl-3a,6a-diazapentalenes with dimethyl acetylenedicarboxylate affords, in an unusual fashion, stable anti-Bredt compounds possessing a 4,10-diazabicyclo[5.2.1]deca-1,3,5,8-tetraene skeleton, the structure of which is confirmed by X-ray crystal structure analysis as well as by 1H and 13C NMR spectroscopy.
