P. Bandiera et al., STEREOSELECTIVE SYNTHESIS OF ENANTIOPURE 6-FLUOROMETHYL FURO[3,4-C]-ISOXAZOLIDINES, Synthetic communications, 28(14), 1998, pp. 2665-2677
The title compounds 7a-c are prepared through a totally regio- and ste
reo-selective intramolecular 1,3-dipolar cycloaddition of nitrones; a
chiral and optically pure sulfinyl function acts as a removable primar
y source of stereocontrol.
