TRIFUNCTIONAL COMPOUNDS ABSORBING UV-RADIATION AND APPLICATION THEREOF Russian patent published in 2015 - IPC C07D249/20 G02C7/04 

FIELD: chemistry.

SUBSTANCE: invention relates to compounds described by formula I. In general formula I: Y-L²-Z-L¹-X, Z stands for bivalent radical of formula (1a):

in which R^3a, R^3b, R^3c and R^1z stand for hydrogen; X stands for monovalent radical of formula

in which R¹ and R² independently represent C₁-C₄-alkyl group, optionally substituted with phenyl; A stands for hydroxygroup or di-C₁-C₄-alkylaminogroup; B stands for 6-membered heterocycle with two nitrogen atoms as heteroatoms; L¹ stands for fragment -C(O)L³C(O)-, where L³ stands for linear or branched C₁-C₄-alkylene radical, or B stands for covalent bond and L¹ stands for fragment -C(O)L³C(O)-O-(CH₂)_p-O-, where p stands for integer number, equal from 1 to 5; or X stands for diphenylphosphine oxide group, L¹ stands for fragment -C(O)L³C(O)-O-(CH₂)_p-Ph-, where Ph is substituted with two C₁-C₄-alkyl groups, where p stands for integer number, equal from 1 to 5; Y stands for monovalent radical -O-C(O)-C(R₁₄)=CH₂, where R₁₄ stands for C₁-C₄-alkyl group; and L² stands for bridge -(CH₂)₂-. Invention also relates to ophthalmological lens, containing polymer, based on invention compounds.

EFFECT: obtained are novel compounds, which can be applied for manufacturing ophthalmological lenses absorbing UV-radiation.
