Preparation of a protected triamino analogue of cholic acid and sequential incorporation of amino acids in solution and on a solid support

We have prepared a triamine derivative of cholic acid with protecting groups on the amines that allow sequential amide formation. The triamine was formed from 3α,7α,12α-trihydroxycholan-24-ol with good stereoselectivity. Sequential removal of the amine pr
