From the juvenile leaves of Eucalyptus blakelyi, a new euglobal, euglo
bal-Bl-1 (1), having a phloroglucinol-monoterpene structure, has been
isolated along with the known euglobals-Ib (2), -Ic (3) and -IIa (4).
The structure and stereochemistry of euglobal-Bl-1 (1) and the stereoc
hemistry of euglobal-Ib (2) were established by spectroscopic evidence
.
