The 3,4-dimethoxybenzyl group was used to N-protect 3,4-diphenyl 1,2-thiazetidine 1,1-dioxide derivatives. It is smoothly eliminated by 2,3-dichloro 5,6-dicyanobenzoquinone (DDQ), the yield depending on the substituents of the 3-phenyl ring.
3,4-二甲氧基苄基用于N-保护3,4-二苯基1,2-噻唑烷1,1-二氧化物衍生物。它可以通过2,3-二氯5,6-二氰基苯并醌(DDQ)平稳地消除,其产率取决于3-苯环的取代基。
