A divergent approach has been developed for the synthesis of some important iminosugars by stereoselective allylation of the lyxosylamine derived from d -lyxose and intramolecular 5- exo -tet ring opening of the epoxide. The strategy described in this paper will be useful for the synthesis of some other biologically active iminosugars for the drug-discovery program.
Dihydroxyacetone Phosphate Aldolase Catalyzed Synthesis of Structurally Diverse Polyhydroxylated Pyrrolidine Derivatives and Evaluation of their Glycosidase Inhibitory Properties
The polyhydroxylated pyrrolidines generated were tested as inhibitors against seven glycosidases. Among them, good inhibitors of α‐L‐fucosidase (IC50=1–20 μM), moderate of α‐L‐rhamnosidase (IC50=7–150 μM), and weak of α‐D‐mannosidase (IC50=80–400 μM) were identified. The apparent inhibition constant values (Ki) were calculated for the most relevant inhibitors and computational docking studies were
