New spirans of the 5,5-dimethyl-3-phenyl-2-oxazolidone series that display photochromic properties in alcohol solutions at about-80/sup 0/C were synthesized. The photoinduced forms are characterized by the presence of two long-wave absorption bands at 350-420 nm and 500-650 nm. The /sup 1/H and /sup 13/C NMR spectra were studied. Anisochronicity of the diastereotopic methyl groups of the oxazolidone ring shows up respectively. only in the /sup 13/C NMR spectra.
