Abstract
An efficient gold-catalyzed protocol for the construction of 1,2-dihydro[c][2,7]naphthyridines from 2-aminophenyl prop-2-yn-1-yl enaminones has been developed. In this organic transformation new C–C and C–N bonds were formedvia6-endo-dig cyclization and good to excellent yields were obtained in one-pot synthesis.
