Abstract
Abstract 2-Hydroxybenzophenone derivatives ( 3a–f ) were synthesized from 2,4-dihydroxybenzophenone ( 1a ) using 4- O -alkylation of the 4-hydroxyl group with 1-(2-chloroethyl)-2,2,6,6-tetramethylpiperidine ( 2a ) and from the carboxyl derivatives of 2-hydroxybenzophenone ( 1b–e ) using the esterification as well as transesterification reactions with the hydroxyl derivatives of 2,2,6,6-tetramethylpiperidine ( 2b–d ) .
