Polyhydroxyamino Compounds via Diene Synthesis with Nitroso Compounds, X. - trans-5,6-Dimethoxy-1,3-cyclohexadiene as Educt for the Synthesis of Optically Active Streptamine PrecursorsThe synthesis and Diels-Alder reactions of the title compound 3 with α-chloronitroso compounds (4, 7) are described. Reaction with the androstane derivative 7 leads highly stereoselectively to the adduct (+)-5a. The enantiomeric excess of this product was determined using several methods, the advantages and disadvantages of which are described.
Notes:
Die Darstellung und Diels-Alder-Reaktionen der Titelverbindung 3 mit α-Chlornitrosoverbindungen (4, 7) werden beschrieben. Bei Verwendung des Androstanderivats 7 erhält man hochstereoselektiv das Addukt (+)-5a, dessen optische Reinheit nach verschiedenen Verfahren vergleichend bestimmt wird.
