Diastereoselective Synthesis of Novel Optically Active Five Membered O- and N-heterocyclic Compounds

Optically active oxetane and cis-but-2-ene-1,4-diol derivatives were used as starting materials in the synthesis of novel five membered heteorcyclic compounds as dihydrofuran and pyrroline derivatives. In addition, new 2,4- disubstituted dioxolane was synthesized diastereoselectively from the diol and the structure of the product was confirmed by NOESY (Nuclear Overhauser Effect Spectroscopy) experiments. Reductive ring opening of the chiral oxetane derivative provided a 3,4-disubstituted-butane-1,4-diol which was used for the synthesis of new chiral pyrrolidine and tetrahydrofuran derivatives.
