Three different bile acid derived biphenylphosphites were synthesised, starting from cholic and deoxycholic acids and biphenol and their stereochemical features checked by CD and NMR spectroscopies. On the basis of the spectroscopic results the capability of the cholestanic system to induce a prevalent sense of twist on the biphenyl moiety of the bile acid derived phosphites as well as their tropos nature was inferred.

Abstract
Three different bile acid derived biphenylphosphites were synthesised, starting from cholic and deoxycholic acids and biphenol and their stereochemical features checked by CD and NMR spectroscopies. On the basis of the spectroscopic results the capability of the cholestanic system to induce a prevalent sense of twist on the biphenyl moiety of the bile acid derived phosphites as well as their tropos nature was inferred.File in questo prodotto:
