Abstract |
In an effort to synthesize carotenoids with improved biological activity, we need to develop a practical synthetic method of diversely R-substituted 4-hydroxybenzoic esters as the terminal ring structure.
A practical two-step synthetic method of diversely R-substituted 4-hydroxybenzoic esters, which may have wide applications in household chemicals and polymeric materials, was developed by 2:1 coupling between ethyl acetoacetate and aldehydes (RCHO) in t-BuOK/t-BuOH, followed by oxidative aromatization of the resulting Hagemman’s esters by using stoichiometric NBS and catalytic TMS.OTf. |
