چکیده
The title compound, C(16)H(17)NO(3), adopts a folded conformation in the crystal structure. The crystal packing is stabilized by inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding inter-actions. The absolute configuration was assigned assuming that the absolute configuration of the starting material l-tyrosine was retained during the synthesis.

The synthesis of the (2S)-[3-(anthracen-9-yl)-4,5-dihydroisoxazol-5-yl]methyl 2-[(tert-butoxycarbonyl)amino]propanoate is obtained through the 1,3-dipolar cycloaddition of the stable anthracenenitrile oxide and the N-Boc protected (S)-alanine allyl ester as dipolarophile. The structure and the fluorescence properties are described upon the relative analytical and spectroscopic data.
