  A new stereoselective approach to a selectively protected derivative of d-pinitol and its evaluation as α-l-rhamnopyranose mimetic

  摘要：

  The synthesis of 3,5-di-O-benzyl-D-pinitol has been stereoselectively accomplished through intramolecular aldolization of 2,6-di-O-benzyl-4-O-methyl-L-lyxo-hexos-5-ulose followed by reduction with NaBH(OAc)(3). Computational analysis [DFT calculations at the B3LYP/6-31G(d) level] suggests that D-pinitol in water largely prefers the conformation corresponding to the (1)C4 one of a alpha-L-rhamnopyranoside unit, being thus a good candidate for its mimicking.
