Abstract
dipyrazolo[3,4-b:4',3'-f][1,5]diazocin-10(1H)-ones 7 were prepared by cyclization of 3-R(2)-1H-pyrazol-5-yl)-1H-pyrazole-5-carboxamides 6 by a Bischler-Napieralski cyclization. A complete assignment of the chem ical shifts to the carbon atoms of compound 7 was performed by differe nt nmr experiments, such as DEFT and XHDEPT for one-bond C-H correlati ons and COLOC experiments for long-range C-H correlations.
