Abstract: A series of novel 3-amino-N-benzyl-1-aryl-1H-benzo[f]chromene-2-carboxamides have been synthesized by the reaction of N-benzyl-2-cyanoacetamide with 2-naphthol and aromatic aldehydes in the presence of piperidine as a base. The chemical structures of all the compounds were confirmed… read more here.

DOI: 10.1016/j.ica.2020.119790
Abstract: Abstract Four water-soluble sodium 8-carboxy-7-hydroxy-6-oxo-6H-benzo[c]chromene-2-sulfonates (2a-2d) were prepared and structurally characterized by 1H NMR, 13C NMR and HRMS-ESI spectra. The experimental results showed that 2a-2d were new water-soluble photoluminescent materials with strong photoluminescence property, large… read more here.

DOI: 10.1039/c8nj03699c
Abstract: A straightforward one-pot vs. stepwise esterification of lapachol was performed to obtain highly diversified heterocycles. Whereas the one-pot esterification leads to mono esterified lapachol, the stepwise approach generated benzo[h]chromene. Furthermore, benzo[h]chromene architectures with embedded triazole… read more here.
