2	Efficient carbohydrate synthesis by controlled inversion strategies Dong, Hai January 2006 (has links) <p>The Lattrell-Dax method of nitrite-mediated substitution of carbohydrate triflates is an efficient method to generate structures of inverse configuration. In this study it has been demonstrated that a neighboring equatorial ester group plays a highly important role in this carbohydrate epimerization reaction, inducing the formation of inversion compounds in good yields. Based on this effect, efficient synthetic routes to a range of carbohydrate structures, notably β-D-mannosides and β-D-talosides, were designed. By use of the ester activation effect for neighboring groups, a double parallel as well as a double serial inversion strategy was developed.</p> Carbohydrate Chemistry Carbohydrate Protection Epimerization Inversion Dynamic Regioselective Control Neighboring Group Participation Organic chemistry Organisk kemi
