We report herein a straightforward and efficient route to prepare 1H-1,2,3-triazoles-linked to 2,3- dihydronaphtho[1,2-b]furan-4,5-dione in C-2 in a one-step reaction from readily available starting materials. We performed a one-step procedure from iodocyclization of 3-allyl-lawsone followed by a nucleophilic substitution reaction of the iodized product, and finally the Huisgen 1,3-dipolar cycloaddition reaction catalyzed by Cu(I) provide 1H-1,2,3-triazol-1-ylmethyl-2,3-dihydronaphtho[1,2-b]furan-4,5-diones.
Quinones, nor-Lapachones, 1, 2, 3-triazoles, one-pot reactions.
