The deamination of pyranose amines. Part II. Methyl 2-amino-2-deoxy-α-D-mannopyranoside
Abstract
The deamination of methyl 2-amino-2-deoxy-α-D-mannopyranoside with nitrous acid gives methyl 2-deoxy-α-D-erythro-hexopyranosid-3-ulose and 2-O-methyl-D-glucose in a ratio of ca. 2:1. The disputed mechanism for the deamination of 2-amino-2-deoxy-D-mannose is further discussed.
