Popis:	The structure of rel-(4S,6R,9S,11S)-1-hydroxy-16-methyl-14-oxapentacyclo[7.4.3.04,15.011,15.06,16]hexadeca-7-ene, C16H22O2, (IV), has been determined. This study thus establishes compound (III), the precursor of (IV), as the first trans,cis,cis,cis[5.5.5.5]fenestrane. The geometry around the central quaternary C atom of (IV) shows relatively little distortion. The C=C bond in the cyclopentene subunit is slightly shorter [1.305 (4) A] than normal. Similarly, small departures from normal are seen in several C–C single bonds.
