IRIDOIDS : AN EFFICIENT CONVERSION OF (-)-CATALPOL INTO (-)-SPECIONIN
Eycken, E. Van der,Janssens, A.,Vandewalle, M.
, p. 3519 - 3520 (1987)
A partial synthesis of the antifeedant (-)-specionin (8) starting from the readily available (-)-catalpol (1) is described.It also allows the formation of analogs of 8 via specific transformations on intermediates 3 or 5 for screening of antifeedant prope
