A facile and highly diastereoselectiveroute to potent natural α-glucosidase inhibitors, i.e., neosalacinol (4) and neoponkoranol (6), isolated from the traditional Ayurvedic medicine “Salacia” was developed by intramolecular cyclization of appropriately substituted sulfides (9 and 12).
time. The key strategy features a coupling reaction between thiol derivatives and a diiodide counterpart. The newly designed thiol coupling partner presents high chemical stability, while the diiodide partner could be easily obtained with increased overall yields compared with conventional routes. The intermolecular nucleophilicsubstitution reaction followed by a diastereoselective intramolecular cyclization

Salacinol and ponkoranol homologues, derivatives thereof and methods of synthesizing and using said homologies and derivatives. The derivatives include stereoisomers, de-O-sulfonated compounds and congeners of the naturally occurring homologues. Some of the derivatives exhibit enhanced glucosidase inhibitory bioactivity in comparison to the naturally occurring compounds which have been isolated from salacia reticulata.
