D-Mannite

When a commercially available C2-symmetric l,4 3,6-dianhydro-D-mannite 29 is chosen as the backbone, reaction of this diol compound with chlorophos-phoric acid diaryl ester gives a series of phosphorate ligands 30. These were tested using the asymmetric hydrogenation of dimethyl itaconate as a model... [Pg.350]

A few efficient bisphosphite ligands have been used for asymmetric hydrogenation of itaconates or a-dehydroamino acid derivatives. Reetz has developed a series of C2-symmetric bisphosphite ligands such as L14, which are based on the structure of 1,4 3,6-dianhydro-D-mannite [78]. The ligands exhibit excellent reactivity and enantioselectivity for the asymmetric hydrogenation of itaconates. [Pg.8]

Die Oxydation von 1,4-Anhydro-D-mannit (9) am Platinkontakt fiihrt zur Bildimg von Mesoweinsaure-mono-glykolsaureather (11), ohne daB eine Zwischenstufe nachgewiesen werden konnte. In analoger Weise entsteht bei der Oxydation von l,4-Anhydro-D,L-talit (12) D,L-Wein-saure-mono-glykolsaureather (14). [Pg.119]

Dianhydro-D-mannit (126), der zwei endo-standige OH-Gruppen enthalt, wird bei 50° C in 6 h nahezu quantitativ zu 1,4 3,6-Dianhydro-D-threo-2,5-hexodiulose (128) oxydiert. Das Monoketon,... [Pg.142]
