FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to novel oxazine compounds of the formula (I): 
wherein X means carbon atom; R1 and R2 mean hydrogen atom; n = 0; A and A' mean independently of one another: (a) linear or branched (C1-C12)-alkyl, (C3-C12)-cycloalkyl; (b) unsubstituted or monosubstituted aryl groups. Also, invention relates to a method for synthesis of photochrome oxazine compounds of the formula (I). Invention provides synthesis of novel compounds and a method for their synthesis used as photochrome compounds.
EFFECT: improved method of synthesis.
