that facilitates the synthesis of new 1,5-dideoxy-1,5-iminoribitol iminosugar C-glycosides 7a–e and 8. The key intermediate in this approach is a six-membered cyclic sugar nitrone that is generated in situ and trapped by an alkene dipolarophile via a [2 + 3] cycloaddition reaction to give the corresponding isooxazolidines 10a–e in a “one-pot” protocol. The iminoribitol C-glycosides 7a–e and 8 were found
