  摘要：

  The absolute configuration at C-2 of 2-carboxy-2-prenyl-4-oxo-1-tetralone (2), a key intermediate in the biosynthesis of prenylnaphthoquinone congeners of the wood and callus tissues of Catalpa ovata, was verified to be S by X-ray crystallographic analysis of the p-bromobenzoate (8) derived from 2.
