  A New Candidate for a Properly Substituted CD Ring Component of Vitamin D3 via Intramolecular Asymmetric Olefination of a 1,3-Cyclopentanedione Derivative

  摘要：

  A highly diastereoselective synthesis of hydrindenone derivative 5 (98% de) was achieved via diastereotopic differentiation of 1,3-cyclopentanedione derivative 4 by intramolecular Horner-Emmons olefination. In addition, the compound 5 was converted to ketone 2, a new building block far 1 alpha,25-dihydroxyvitamin D-3 (1).
