โฆ Synopsis
Grayanotoxin (G) II (L)"?
a toxic diterpenoid isolated together with other related grayanoids 1) from Leucothoe grayana Max., is characterized by the A-nor-B-homo-kaurane skeleton and by the dense arrangement of functionality.
We report herein a partial synthesis of G II from a tricyclic degradation product 2, which is in principle synthetically accessible by a number of routes.
The following processes therefore open a way to a relay total synthesis of G II.
