Gluconic 2-amino-2-deoxy-

Deamination of 2-amino-2-deoxyaldonic acids with nitrous acid has been shown to give 2,5-anhydroaldonic acids with overall retention of the configuration of C-2. The reaction parallels the deamination, with nitrous acid, of a-amino acids that leads to a-hydroxy acids with retention of configuration.19,29 Thus, the formation of 2,5-anhydro-D-gluconic acid27 (15) from 2-amino-2-deoxy-D-gluconic acid (14) has... [Pg.116]

A methoxylated polyamide 78 analogous to Nylon 6 was obtained in several steps fi om D-glucose [61, 63] through the preparation of a dimeric active ester of 6-amino-6-deoxy-2,3,4,5-tetra-(9-methyl-D-gluconic acid (49). This polyamide was highly crystalline, and gave resistant films with a spherulitic texture. [Pg.162]

Anhydroaldonate derivatives are formed in good yield when 2-amino-2-deoxyaldonic acids are deaminated. Thus, deamination of 2-amino-2-deoxy-L-(and D-)gluconic acid was used to form the tetra-... [Pg.70]

It was incorrectly stated in Ref. 6 that the methyl ester of 2-amino-2-deoxy-L-gluconic acid was used, and an incorrect structure for normusearine was given. [Pg.71]

During the deamination of 2-amino-2-deoxy-D-gluconic acid, it is probable that the carboxyl group is involved in a participation reaction with the carbonium cation CVIII from the side of the molecule opposite to the departing diazo group, to give an intermediate CIX with the d-manno con-... [Pg.260]
