✦ Synopsis
Grayanotoxin-II (1) and its dihydroderivatives can be oxidized with leadtetraacetate to corresponding secoketones which easily isomerize by alkaline treatment into respective tetrahydroxyketones (2).
This paper deals with a circumstantial examination of the isomerization reaction towards both secoketone(1) and secoketone triacetate(I1) obtained from Grayanotoxin-II and its triacetate respectively, and also with the stereochemis-
