, p. 211 - 219 (2007/10/03)
A new analogue of vicenistatin was isolated from the producing strain Streptomyces sp. HC-34. A characteristic of the elucidated structure involved the existence of a neutral sugar mycarose instead of an aminosugar vicenisamine of vicenistatin. The absolu
Effect of nitrogen substitution on the diastereoselection of intramolecular nitrone/alkene cycloadditions
Baldwin,Gedon
, p. 587 - 596 (2007/10/02)
The diastereomeric ratios of several intramolecular nitrone/alkene cycloaddition reactions have been shown to be sensitive to the substituent on the nitrone nitrogen in a double diastereodifferentiation process.
Stereospezifische Darstellung C-methylverzweigter Kohlenhydrate mit Tetramethylzirkonium(IV)
Kauffmann, Thomas,Klaffke, Werner,Philipp, Christian,Thiem, Joachim
, p. 33 - 38 (2007/10/02)
Branched glycals and glycosides containing an HO-C-CH3 group were obtained stereospecifically by the action of tetramethylzirconium(IV), upon either α,β-unsatured enuloses or pyranosiduloses.L-Olivomycal and the C-4 epimer of L-mycaral were obtained from
Syntheses and Reactions of 3-C-Methyl-branched Glycals of the D-Series. Preparations of the Isomers of Terminal Disaccharides in Olivomycin A and Mithramycin

, p. 1442 - 1454 (2007/10/02)
Syntheses of D-olivomycal (6) and D-mycaral (9) are achieved starting with D-rhamnal (4) or D-digitoxal (5), respectively.The transformation of 9 to methyl α-D-mycaroside (12) represents a configurational assignment at the branching point.With methyllithi
Synthesen biologisch wichtiger Kohlenhydrate, 24. Derivate des Sibirosamins (4,6-Didesoxy-3-C-methyl-4-methylamino-D-altropyranose) durch 4 -> 2-Chiralitaetstransfer und vic. cis-Oxyaminierung eines 3-C-Methyl-hex-3-enopyranosids

Methyl 4-O-benzoyl-2,6-didesoxy-3-C-methyl-α-D-ribo-hexopyranoside (14) yields the D-erythro configurated 3-C-branched hex-2-enopyranosides 15 and 16, resp., with high selectivity by elimination with thionyl chloride. 16 is transformed with complete inver
