Reactions of 4-oxobutanoic acids as well as their cyclic analogues 3H-furan-2-ones with 1,3-binucleophilic reagent (2-aminophenyl) methanol lead to the formation of 1-R-5H-benzo[d]pyrrolo[2,1-b][1,3]oxazines and 3a-R-2,3,3a-trihydro-5H-benzo[d]pyrrolo[2,1-b][1,3]oxazin1-ones, respectively. Quantum-chemical calculations of the Fukui reactivity indices and local hardness have substantiated the mechanisms of the reactions carried out.

Higher fungi – basidiomycetes play significant role as food and biological subjects for establishing the regularities of the living systems’ operation, development and response to the different-nature effectors impact. Insufficient activity of the living organisms’ antioxidant system interfering the ability of overcoming the negative consequences of oxidative stress (excessive level of free radicals in cells) is believed to be a reason for the organisms aging and death.
