The synthesis and biologicalactivity of novel CD-ring modifiedanalogues of 22-oxa-1alpha,25-dihydroxyvitamin D(3), lacking the D-ring and featuring a connection between C-12 and C-21 (cis-perhydrindane CE-ring analogues), is described. The synthesis of the CE-ring system follows Meyers' methodology for the preparation of enantiomerically pure hydrinden-2-ones. The analogues show a complete lack of
