Alkylamino-arabinofuranoses

The direct synthesis of amino-oxaphosphinanes 160 and 161 was performed starting from alkylamino-arabinofuranose 159, directly obtained by the treatment of... [Pg.76]

By contrast, better diastereoselectivity was observed in the synthesis of 3-amino-oxaphosphinanes 42a and 42b (Scheme 9). Then mixing alkylamino-arabinofuranoses 41, directly prepared from the reaction of 2,3,5-tri-O-benzyl-D-arabinofuranose 38 with an excess of a primary amine (i.e., benzylamine or aUylamine), gave mainly one diastereomer with a glucosamine-like stereochemistry (42a or 42b). [Pg.142]
