5-Thio-D-allose

Most of the other important 5-thiopyranoses such as 5-thio-D-mannose (32) [55], 5-thio-D-galactose (33) [56], and 5-thio-D-allose [57] have been synthesized. [Pg.2006]

Thioaldohexoses can also be prepared by transformation of previously formed 5-thio sugars. Thus, 5-thio-D-allose (337) was prepared from the D-gluco-... [Pg.63]

The following are not substrates D>allose, D-galactose 4-deoxy-glucose, 4>deoxy-fluoroglucose, 5-thio-D glucose, L-rhamnose, L-fucose, L-sorbose. [Pg.27]

Deoxy-4-thio-D>gulose (174) has been synthesized by the route shown in Scheme 62. This thio-sugar showed little tendency to adopt the five-membered ring form containing the sulphur atom, either as the free sugar or under acetolys-ing conditions. An unsuccessful attempt to synthesize derivatives of 6-deoxy-4> thio-D-allose was also reported. Treatment of ethyl 3,5,6-tri-0-acetyl-2-5 -ethyl-1,2-dithio-a-D-mannofuranoside (175) with bromine furnished an unstable... [Pg.77]
