Abstract
The spatial structure of 1(10)Z, 4Z-hanphyllin has been established by the x-ray method. A new conformation of the ten-membered ring in Z, Z-germacranolides has been found - the15 D 5,1 D 14 boat-boat type. The probabilities of the realization of the conformers of this compound and of its C3-epimer have been calculated by the method of molecular mechanics.
