Synthesis of 2,7-diazabicyclo[22.1]heptenes by N-O bond cleavage of arylnitroso diels-alder 1,2-dihydropyridine cycloadducts

Article abstract of DOI:10.1055/s-0034-1378682

The cleavage of the N-O bond of nitrosoarene-derived cycloadducts with 1,2-dihydropyridines gives different products depending on the protecting group of the starting dihydropyridine and reaction conditions. The use of catalytic amounts of CuCl in non-nuc
