摘要
An exceptionally short synthesis of novel indolizidine-, quinolizidine-, and piperidine-based iminosugars from unprotected 2-deoxy-d-ribose by intramolecular 1,3-dipolar cycloaddition of sugar-derived N-(3-alkenyl)nitrones has been accomplished. The use of the 2-deoxy carbohydrate also enabled us to confirm the previously proposed mechanism for the alteration of the stereochemical course of the intramolecular 1,3-dipolar cycloaddition observed for an unprotected sugar-derived nitrone. Biological assays of the six new iminosugars revealed a slight inhibition activity of the indolizidine derivative 7a, whereas, interestingly, the two quinolizidine iminosugars 5a and 5b appeared to be weak glycosidase activators.
