Abstract

The 1,3-dipolar cycloadditions of pyrroline N-oxide (1) with (1R,2S)-trans-2-phenylcyclohexyl- and with (1R,2S,5R)-8- phenylmenthyl-pent-2-enoates (9 and 10) proceed with opposite diastereoselectivities. The two enantiomers of a new dihydroxyindolizidine, (+)-6 and (-)-6, were synthesized using 4 and 5, respectively, as the chiral auxiliary.
