Stereospecific synthesis of pyrrolidines with varied configurations via 1,3-dipolar cycloadditions to sugar-derived enones
Enantiomerically pure pyrrolidines have been obtained by 1,3-dipolar cycloaddition of stabilized azomethine ylides and sugar enones (dihydropyranones) derived from pentoses. Thus, the S-enone (menthyl 3,4-dideoxy-(1S)-pent-3-enopyranosid-2-ulose) was prepared from d-xylose, while the R analogue was...
