The four possible stereoisomers of a new metabolite of vitamin D3, 25-hydroxycholecalciferol-26, 23-lactone, have been synthesised; we establish that the natural product has the 23R, 25S stereochemistry, and that it has <1% of the activity of vitamin D3 in bringing about intestinal calcium absorption.
