Synthèse des 2-amino-2-désoxy-d-arabinono- et -d-xylono-lactones par condensation d'acides aminés avec le d-glycéraldéhyde. Analyse structurale par rayons X de deux dérivés
Abstract Synthesis of 2-amino-2-deoxy- d -pentonolactones was performed by diastereoselective hydroxyalkylation of 2,3-O-isopropylidene- d -glyceraldehyde with ethyl isocyanoacetate, to give two oxazolines in a ratio of 7:3. Hydrolysis gave first the corresponding amides, and then the 2-amino-2-deoxypentonolactones. The structure of the 2-amino-2-deoxy- d -arabinono-1,4-lactone was established by X-ray
