(3S,11Z)-14,16-Dihy-droxy-3-methyl-3,4,5,6,9,10-hexa-hydro-1H-2-benz-oxacyclo-tetra-decine-1,7(8H)-dione (cis-zearalenone): a redetermination.

ABSTRACT: The title compound, also known as cis-zearalenone (cis-ZEN), C(18)H(22)O(5), has already been reported elsewhere [Griffin et al. (1981 ?). ACA Ser.29, 35], but no atomic coordinates are publicly available. The mol-ecule is of inter-est with respect to its toxicity. In the crystal, intra-molecular O-H?O hydrogen bonds stabilize the mol-ecular conformation, while inter-molecular O-H?O hydrogen bonds link the mol-ecules to form infinite chains along the [110] and [1-10] directions. The absolute configuration has been assigned by reference to an unchanging chiral centre in the synthetic procedure.
