    • Abstract


      The ultraviolet spectra of methyl-α-o-carboxyphenyl cinnamates and α-o-carboxyphenylcinnamic acids is reported. These compounds possess the characteristiccis stilbene spectral curve, thereby supporting Loewenthal and Pappo’s suggestion that these compounds havecis Ph/Ph-COOR configuration. Formation of this isomer in the Stobbe reaction of dimethyl homophthalate and aryl aldehydes has been rationalized as proceedingvia the erythro conformer of the oxyanion.
