2-functionalized-3,5-bis(hydroxymethyl)pyrrolidines is described. The method uses 2-azabicyclo[2.2.1]hept-5-enes, readily obtained from glyoxylates of aliphatic amines and cyclopentadiene, as starting material. The hydroxylation of the double bond followed by the oxidative cleavage of the six-membered ring and in situ reduction of the dialdehyde intermediate gives the title pyrrolidines.

Diels–Alder reaction of protonated N-benzyl imine of methyl glyoxylate with cyclopentadiene in different solvents gave mixtures of exo/endo adducts. The exo/endo selectivity of the reaction was elucidated by NMR experiments. Theoretical calculations by means of density functional theory (DFT) at the B3LYP/6-31G(d) level have also been performed to elucidate the molecular mechanism of this reaction. The DFT
1.0 2,4 ]oct-6-ene-4-carboxylates. The key steps in the synthetic strategy are dihydroxylation with osmium tetroxide/ N-methylmorpholine N-oxide, oxidative cleavage with sodium periodate, and reduction using sodium borohydride or lithiumaluminum hydride; overall yields ranged from 40-60%.
