Stereocontrolled synthetic entries to homochiral hydroxylated norbornene derivatives. Formal synthesis of some carbocyclic nucleosides.
摘要:
Several homochiral hydroxylated norbornene derivatives have been synthesized from D-mannitol. Stereocontrolled Diels-Alder cycloadditions and stereospecific hydroxylations are key processes for the creation of the stereogenic centers in the target molecules. These compounds are real or potential precursors in the synthesis of carbocyclic nucleosides and related products.

chiral precursor. The target molecules include pairs of enantiomers and their configuration has mainly been assured by controlling the facial and the endo/exo diastereoselectivity in the Diels-Alderreactions of chiral cyclic or acyclic dienophiles. Some of the products obtained are key intermediates in the synthesis of biologically active compounds.
