Abstract

An efficient one-pot synthesis of a library of novel sugar-based spirooxindole-pyrrolidines or -pyrrolizidines has been accomplished by [3+2] cycloaddition. This method utilizes an azomethine ylide derived from isatin and sarcosine or l-proline with an α,β-unsaturated β-C-glycosidic ketone as the dipolarophile. All these sugar-based heterocyclics were characterized by NMR (¹H and ¹³C), HPLC, and elemental analysis
