Isolation and structure elucidation of vicenistatin M, and importance of the vicenisamine aminosugar for exerting cytotoxicity of vicenistatin
Matsushima,Nakayama,Fujita,Bhandari,Eguchi,Shindo,Kakinuma
, p. 211 - 219 (2001)
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
An Improved Procedure for the Ring Opening of Benzylidene Acetals with N-Bromosuccinimide

, p. 1589 - 1596 (2007/10/02)
A new procedure for the ring opening of 4,6-O-benzylidene acetals of carbohydrates with N-bromosuccinimide using calcium carbonate in stoechiometric amount instead of excess barium carbonate is described.This procedure is succesfully applied to some highl
SYNTHESIS OF THE DISACCHARIDE C-D FRAGMENT FOUND IN EVERNINOMICIN-C AND -D, AVALAMYCIN-A AND -C, AND CURAMYCIN-A: STEREOCHEMISTRY AT THE SPIRO-ORTHOLACTONE CENTER
Beau, Jean-Marie,Jaurand, Guy,Esnault, Jacques,Sinay, Pierre
, p. 1105 - 1108 (2007/10/02)
The two isomers at the spiro-ortholactone center of the disaccharide C-D fragment of orthosomycins have been synthesized.Their mild acidic hydrolysis was under stereoelectronic control with each isomer leading to only one ester.It is therefore possible, f
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
Thiem, Joachim,Elvers, Juergen
, 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
Dyong, Ingolf,Schulte, Gerhard
, p. 1484 - 1502 (2007/10/02)
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
