Sterically hindered phenols are the most interesting among the known 
antioxidants through the variety of chemical properties and biological activity. 
The presence in the molecule of several reaction centers provides inhibition of 
oxidative processes by different mechanisms: hindered phenolic moiety is 
realize antiradical defense, the phosphoryl moiety is responsible for the ability 
to inhibit the reactions of hydroperoxides nonradical destruction. 
The interaction of methylenequinones 1-3 with propane-1,3-diol,  
2,2-dimethylpropane-1,3-diol, butane-1,3-diol, butane-1,4-diol,  
N1, N1-dimetiletane-1,3-diamine, N1, N1-dimethylpropane-1,3-diamine results 
in new antioxidants 4-11, containing phosphoryl and sterically hindered 
phenol structural fragments. 
 
 
 
The structure of synthesized compounds was proved by NMR 1H, 31P, 
13С, IR spectroscopy, mass spectroscopy (MALDI) and element analysis.
