Mannopyranoside methyl 4-amino-4,6-dideoxy

Participation of the ring-oxygen atom has also been postulated,124 to account for the stereospecific formation of L-mannopyranoside (40) and D-allofuranoside (41) products in the deamination, by way of 39b, of methyl 4-amino-4,6-dideoxy-2,3-0-isopropylidene-a-L-man-nopyranoside (39a). Ring contraction to give furanoside products pre-... 

Perosamine was obtained as an amorphous hydrochloride on hydrolysis of perimycine, and possesses the structure of a 4-amino-4,6-dideoxy-D-mannopyranose hydrochloride. Methyl 4,6-dideoxy-4-(dimethylamino)-a-L-mannopyranoside is formed by the ring opening of methyl 3,4-anhydro-6-deoxy-a-L-talopyranoside with dimethyl-amine. Other naturally occurring 4-amino sugars are a 2,4-diamino-...

Kenne and co-workers obtained the azide (18), and thence various H-acylated methyl 4-amino-4,6-dideoxy-a-D-mannopyranosides for use in a and C-n.m.r. study, by the action of sodium azide on the known 4-bromide (20). ...
