Isoretronecanol was stereoselectively synthesized using 1,3-dipolar addition of pyrroline oxide to dihydrofuran and a new cyclization of δ-amino alcohol to pyrrolidine.

The 1,3-dipolar cycloaddition reactions of various Z- and E-nitrones with ethyl vinylether and 2,3-dihydrofuran are catalyzed by 20 mol% of chiral oxazaborolidines at room temperature. The effect of high pressure on these reactions is discussed.
