Regioselective bromination of D-pentono-1,4-lactones with SOBr 2 in DMF led to 5-bromo-5-deoxy derivatives. These intermediates were treated with LiN 3 and hydrogenated to give 5-amino-5-deoxy-D-pentonolactams in 60–83% overall yield.

Treatment of unprotected d -ribono, d -arabinono and d -xylono-1,4-lactones with either thionyl chloride or thionyl bromide in dimethylformamide led to 5-chloro- or 5-bromo-5-deoxy derivatives in 70%–95% yields. Under the same conditions, d -lyxono

Reaction of cysteamine with d-ribofuranose in which a 2,3-O-isopropylidene group was introduced, yielded the 2-(S)-thiazolidine derivative stereoselectively. The following step of cyclisation led to castanospermine and australine analogues, 3 and 4,
