T. Geller et al., PREPARATION OF HELIOPORIN-D FROM THE SECO-PSEUDOPTEROSIN AGLYCONE - REVISION OF THE STEREOSTRUCTURE OF HELIOPORIN-D, Tetrahedron letters, 39(12), 1998, pp. 1541-1544
A revised stereostructure for helioporin D was unequivocally establish
ed by its synthesis from the seco-pseudopterosin aglycone and by caref
ul analysis of NMR data. As the corresponding benzodioxole derived fro
m the pseudopterosin A aglycone was not identical with helioporin E, i
t was proven that helioporin D and E do not belong to the same stereoc
hemical series. (C) 1998 Elsevier Science Ltd. All rights reserved.
