G. Ismailova et al., Synthetic analogs of natural flavolignans IX. Synthesis of 3-amino-substituted analogs of hydnocarpin, CHEM NAT CO, 35(2), 1999, pp. 159-161
New S-amino-substituted chromones with I,3-benzodioxan and I,4-benzodioxan
nuclei in position 2 have been synthesized. The structures of the compounds
obtained have been confirmed by their PMR spectra.
