Synthesis of Retiferol RAD1 and RAD2, the Lead Representatives of a New Class of des-CD Analogs of Cholecalciferol

The design and total convergent synthesis are described for the leading representatives of the new class of analogs of cholecalciferol with the CD-ring system replaced with a two-carbon aliphatic spacer.The leading representatives of C21 retiferols (RAD1

Studies on a Convergent Route to Side-Chain Analogues of Vitamin D: 25-Hydroxy-23-oxavitamin D3

Permanganate oxidation of vitamin D3 affords the 7,8-diol 4a, which was successively silylated to 4b and then oxidatively cleaved and reduced to afford 3c.The latter was converted in several steps to phosphine oxide 3b, a useful A-ring fragment for analog
