| Abstract: | The main biosynthetic route from 4-(2′-carboxyphenyl)-4-oxobutanoic acid (1) via 2-carboxy-4-oxo-1-tetralone (COT) to several quinonoids in callus cultures of Catalpa ovata was definitely demonstrated to pass stereospecifically through (2S)-prenyl-COT ((2S)-2) and (2R)-catalponone ((2R)-3). |
