Novel Convergent Synthesis of Side-Chain-Modified Analogues of 1α,25-Dihydroxycholecalciferol and 1α,25-Dihydroxyergocalciferol

A novel synthetic strategy for the preparation of side-chain-modified analogues of 1α,25-dihydroxycholecalciferol and 1α,25-dihydroxyergocalciferol was developed as a part of the extensive synthetic search for vitamin D analogues of potential anticancer a
