Lituarine SyntheticStudies.An Efficient, Stereocontrolled Construction of the Common C(7-19) Tricyclic Spiroketal Fragment.Page 3982, Figure 1.Two structures were numbered incorrectly; the correct numbers are shown below.Page 3980, reference 9.The predicted equilibrium ratio of the C(16) epimers of 4 should read 5.3:1.These calculations do not support the speculation that the experimentally derived ratio of 1.4:1 is at equilibrium (page 3982).
