A chromatography-free, six-step, diastereocontrolled synthesis of (±)demethoxymethyl-daunomycinone is described. The tetracyclic carbon skeleton is elaborated by a Diels–Alder strategy in which the 6a,7 10a bonds are constructed, the epoxytetraone and the diene serving as precursors.
HydrolyCited by: 7. A convergent synthesis of (+)demethoxydaunomycinone and (+)-daunomycinone via annelation of a functionalized quinone monoketal with the anion of the corresponding 3-cyano-l(3H)isobenzofuranone is reported.
The quinone monoketal, sequence, was prepared without chromatography from 2,5-dimethoxybenzaldehyde in sixteen by: An efficient enantiocontroUed synthesis of(+)demethoxydaunomycinone Table 3.

Abstract. Anthracyclinones and the glycosidic anthracyclines are pigments, ranging in color from yellow to purple, which are produced by various species of Streptomyces (1, 2, 3).The very descriptive name anthracyclines was coined by Brockmann (1) and is derived from anthraquinones and the likewise tetracyclic antibiotic properties of the anthracyclines were observed soon Cited by: 4.
Enantioselective synthesis of (+)Demethoxy-1,4-Dimethyldaunomycinone Article in Bioorganic & Medicinal Chemistry 10(3) April with 22 Reads How we measure 'reads'. Leonard Cockayne, who settled in New Zealand inintroduced the study of seedling forms, plant ecology, and plant hybridization.
Knowledge of economic native plants was advanced by his many studies, including a report on the ecology and management of beech (Nothofagus) forests, and his book on the cultivation of native plants (Cockayne ).

The efficacy of anthracycline antibiotics such as daunomycin and adriamycin in the treatment of a variety of human malignancies has stimulated a continued interest in the synthesis of this class of antitumor agents [1,2,3].
Unfortunately, their clinical use is limited by a number of problems, including intrinsic and acquired drug resistance and Cited by: 5. This banner text can have markup. web; books; video; audio; software; images; Toggle navigation. Dernière Activité. Mes documents. Documents sauvegardés.
