Abstract: The invention relates to a method for coating sheet-form textile materials, in which there is applied to a sheet-form textile material an aqueous dispersion containing anionically modified polyurethane ureas comprising (A) aromatic diisocyanate, (B) polyether polyol having a mean molecular weight greater than 1500, (C) at least one compound containing from 1 to 2 isocyanate-reactive groups and at least one ionogenic group, (D) polyamine having a mean molecular weight of at least 32, and (E) water, wherein the mean total functionality of the isocyanate-reactive compounds B to D is from 1.85 to 2.2, the molar ratio of the isocyanate groups of component A to the isocyanate-reactive groups of components B to D is greater than 1, and the polyurethane ureas have a content of from 800 to 1500 mmol of urethane groups/kg of anionically modified polyurethane urea and a content of from 800 to 1800 mmol of urethane plus urea groups/kg of anionically modified polyurethane urea.

Abstract: The present invention relates to polyurethane ureas dissolved in organic solvents, which may be used as an adhesive coat for the coating of textiles.

Abstract: The invention relates to a novel process for the preparation of an aminoalcohol of the formula racemically or optically active, starting from 2-azabicyclo[2.2.1]hept-5-en-3-one, its further conversion to give the corresponding acyl derivative and its further conversion to (1S,4R)- or (1R,4S)-4-(2-amino-6-chloro-9-H-purine-9-yl)-2-cyclopentenyl-1-methanol of the formulae In the latter synthesis, the aminoalcohol is converted into the corresponding D- or L-tartrate, which is then reacted with N-(2-amino-4,6-dichloropyrimidin-5-yl)formamide of the formula to give (1S,4R)- or (1R,4S)-4-[(2-amino-6-chloro-5-formamido-4-pyrimidinyl)amino]-2-cyclopentenyl-1-methanol of the formulae and then cyclized to give the end compounds.
