Anti-inflammatory activities of α-truxillic acid derivatives and their monomer components

The anti-inflammatory activities of α-truxillic acid (1) and 4,4′-dihydroxy-α-truxillic acid (2) as well as their monomer components (E)-cinnamic acid (3) and (E)-p-coumaric acid (4) were evaluated in the formalin test. α-Truxillic acid (1) and its deriva

Remarkably high homoselectivity in [2 + 2] photodimerization of: Trans -cinnamic acids in multicomponent systems

[2 + 2] homoadducts were exclusively obtained with total regio- and stereo-selectivities when a suspension of several solid photoactive trans-cinnamic acids in cyclohexane was stirred and irradiated.

Templating photodimerization of trans-cinnamic acids with cucurbit[8]uril and γ-cyclodextrin

(Chemical Equation Presented) Cucurbit[8]uril and γ-cyclodextrin are able to align two olefin molecules in a head-head fashion within their large cavities. Excitation of such templated olefins results in syn head-head cyclobutanes in nearly quantitative yields. The methodology revealed here works with trans-cinnamic acids that do not dimerize either in solution or in the solid state and with the ones that yield only anti head-tail dimer in the solid state.
