Asymmetric Synthesis of a Key 1α,25-Dihydroxy-Vitamin D3 Ring A Synthon

An efficient and highly stereoselective synthesis of the A-ring synthon 4 of 1,25(OH)2-vitamin D3 (1) is deascribed.The aldehyde 12, which was used for an intramolecular ene reaction to form the main framework 18, was obtained by two different asymmetric
