New synthetic routes to the four possible 3,7-dihydroxy acids are described.The principal reactions involved were inversions with DMF and Me2SO-crown ether and reduction of 12-oxo tosylhydrazones.Inversion of 3α-tosylates by the Me2SO-crown ether method succeeded but that of the corresponding mesylates did not.A table of 1H NMR chemical shift reference data of monosubstituted methyl cholanates pertinent to bile acid characterization has been expanded.
