Epoxidation of the Δ7-Double Bond of Vitamin D3. X-Ray Structure Determination of Its 4-Phenyl-1,2,4-triazolin-3,5-dione Adduct. A Structure Revision

Epoxidation of vitamin D3 with MCPBA yields exclusively the 7,8-monooxirane.Its 7R,8R stereochemistry was established by X-ray analysis of the PTAD-adduct-derivative.This result corrects the stereochemical assignment in a previous publication.
