Ph.D. thesis. Typescript.
Still valid and useful after up to a decade, this series presents critical reviews of the present position and future trends in modern chemical research. It is made up of short and concise reports on chemistry, each written by the world renowned experts. 6-(1'-Formyl)-1,5-dimethoxy(2″-oxopropyl) anthraquinone (1), a key intermediate in Danishefsky's synthesis of vineomycinone B2 methyl ester (5), has been prepared by a new route from anthrarufin (6) via the intermediate 1-methoxy(2′-methylprop-2′-enyl)(2′-methylprop-2′-enyloxy) anthraquinone (20). An alternative synthesis of the diketone (40) has been achieved via Claisen Cited by: 6.
Abstract. Anthracyclinones of the rhodomycinone type (type A) can efficiently be synthesized by Marschalk reaction of hydroxy aldehydes diastereoisomeric cyclization products 2 and 3 are obtained in aqueous-methanolic reaction medium but the natural configuration 2 is formed almost exclusively under phase transfer : K.

Convergent syntheses of the benz[a]anthraquinone natural products X C (2c) and ochromycinone (2d) have been achieved using aromatic directed metalation steps involve (a) the condensations of dilithiated cis-tetralol (13a) with the aldehydo o-anisamide 14 and of methoxymethyl protected aldehyde 17b with lithiated o-anisamide (18) to give, after acid-catalyzed cyclization Cited by: The stereochemical features involved in electrophilic additions to the ring A moiety in diazatetracyclic analogues of anthracyclinones have been investigated. The 1-methyl and 1,3-dimethyl derivatives 2a and 2b were selected as the substrates and made to react with bromine azide, iodine azide, and NBS–EtOH in order to evaluate the influence Cited by: 4.

An efficient method for the enantio- and diastereo-controlled construction of potentially tertiary alcohol by alkylation of an α-cyano-carbanion derived from 1,2-O-isopropylidenedeoxy-β-L-threo-pentofuranuronitrile 6 as chiral template has been developed; the method has been applied to the stereocontrolled synthesis of optically active 4-demethoxy feudomycinone C 4.
Reaction of 3-C-ethynyl-1,2-O-isopropylidene-α-D-ribo-pentodiaido-1,4-furanose (2b) with leuco-quinizarin (4) in alkaline solution gave a mixture of (5S)- and (5R)C-ethynyl-1,2-O-isopropylidene(quinizarinyl)-α-D-ribofuranose (11a) and (11b) respectively and the corresponding 5-deoxyderivative (11c).Acid-catalysed hydrolysis of the furanoses (11a) and (11b) furnished the quinizarinyl.
The book also explains its significance in chemistry and other related fields. The text also mentions the different plant and animal origins of these compounds. The book covers the biogenesis and distribution of these organic compounds; their identification and spectra; and the different kinds of quinolones, which include benzoquinones, naphthaquinones, julichromes, and laccaic acids.
