Azetidines and their n-oxides - antioxidants polymerization inhibitors and biologically active

摘要

Cpds. are of formula (I): (where R1, R2, R3, R4 are alkyl; R5 is H, OH, benzoyloxy, -CH2OH; R6 s OH, benzoyloxy; or R5, R6 and the attached C- atom may be represent and their free N-oxide radicals of formula (II) : (I) are inters. for (II) and also have unspecified biological activity. (II) are antioxidants, polymsn. inhibitors, reaction initiators and also capture free radicals.
