New Access to 1-Deoxynojirimycin Derivatives via Azide−Alkene Cycloaddition
摘要:
The synthesis of 1-deoxynojirimycin (DNJ) derivatives is described from D-glucono-delta-lactone. The DNJ derivatives were obtained via a sequence that included a stereoselective intramolecular Huisgen reaction, decomposition to an aziridine, and its subsequent reaction with a nucleophile. Minimization of allylic strain in the transition state accounts for the stereoselectivity of the cycloaddition reaction.

Synthesis of compounds with characteristics of natural products are required to increase the diversity and biological relevance of compounds for screening. These include new frameworks/scaffolds, with multiple stereogenic centres and various functional groups. Carbohydrates are renewable, readily available and have stereochemical diversity and functionality. Herein, building blocks derived from monosaccharides
