- 中文摘要: 4-Oxo-1,1,3-cyclohexanetricarboxylic acid trialkyl esters in deuterochloroform and dimethylsulfoxided/sup 6/(DMSO) exist exclusively in the enol form. The keto form is the major component in the analogous compounds of five-membered ring. The 1,3- interaction between carboalkoxy groups in the six-membered ring should be the reason why the carboalkoxy group at 3-position is in equatorial configuration and engages in the intramolecular hydrogen bond, so that the enol form is dominating.
