Method for obtaining new bicyclic iminosugars

摘要

process to obtain new compounds of general formula 1, in the reaction of hydroxylamine with a sugar in which in the first stage, n - (2 - metylopent - 4 - en - 2 - yl) hydroksyloaminu0119 or n - (5 - allyl - 2,2-dimethyl - l, 3 dioxane - 5 - yl) hydroksyloaminu0119 undergo reaction with 2,3 - - izopropylideno - d - rybofuranoz s or 5 - - dimetylotertbutylosililo - 2,3 - - izopropylideno - d - rybofuranozu0105,and then separates the mixture of products. the second stage depends on the type of podstawnika in conjunction of transition, and the third stage is the reaction of hydrogen with a catalyst metal, and then with water and alcohol solution of a strong acid.
