摘要
The title compound,ethyl 2-（2-amino-3-ethoxycarbonyl-4H-benzo[f]chromene-4-yl） cyanoacetate 4,has been synthesized and its crystal structure was characterized by X-ray single-crystal diffraction.The crystal belongs to monoclinic,space group P21/n with a=12.9408（18）,b=11.1870（13）,c=13.8975（19）,β=109.261（2）°,Z=4,C21H20N2O5,Mr=380.39,V=1899.3（4）3,Dc=1.330 g/cm3,μ=0.096 mm-1,F（000）=800,S=1.027,R=0.0535 and wR=0.1012 for 1365 observed reflections（I 2σ（I））.X-ray analysis reveals N–H…π interactions,π…π interactions and hydrogen bonds in the title molecule.
