Abstract
Daidzin 1, genistin 2, ononin 3 and sissotrin 4 are the major products of the phase transfer catalysed reaction between the isoflavone aglycones daidzein, genistein, formononetin and biochanin A, respectively, and 1-bromo-2,3,4,6-tetra-O-acetyl-α-glucopyranose. Complete proton and carbon NMR assignments are presented for compounds 1–4.
