Methyl 9-hydroxy-15-methyl-2-oxo-11-(pyren-1-yl)-10-oxa-15-azatetracyclo[7.6.0.01,12.03,8]pentadeca-3(8),4,6-triene-12-carboxylate

In the title compound, C32H25NO5, the furan and pyrrole rings each adopt an envelope conformation, the respective flap atoms being the C atom bearing the pyrene substituent and the CH2 atom adjacent to the N atom. The molecular conformation is stabilized by an intramolecular O—H...N hydrogen bond. In the crystal, C—H...O contacts link the molecules, forming a two-dimensional network parallel to (001).
