An efficient convergent synthesis of the iodide 6a, which contains the vitamin D triene system, and the ultrasonically induced reactions between 6a and 6b and electron-deficient olefins to give several vitaminD3 analogues with modified side chains are described.

The invention provides carriers that enhance the absorption, half-life or bioavailability of therapeutic compounds. The carriers comprise targeting groups that bind the Vitamin D Binding protein (DBP), conjugation groups for coupling the targeting groups to the therapeutic compounds, and optionally scaffolding moieties.
