SYNTHETIC APPROACH TO GRAYANOTOXINS AND ASEBOTOXINS: A NEW CONSTRUCTION OF THE A-HOMOGRAYANOTOXANE RING SYSTEM

The tetracyclic compounds (3 and 4) corresponding to A-homograyanotoxane system were synthesised by a thermolysis of the benzocyclobutene (8), followed by a Wagner-Meerwein rearrangement of the kaurane type of compounds (15 and 16).
