At the Bayer AG Lockhoff [31, 32] prepared a new potentially useful product of the U-4CR with four different carbohydrate derivatives as educts.
2] = 10 000 constitutionally different products can be prepared from two types of components where each of them contains 100 different educts, whereas (100)2 = 100 000 000 different U-4CR products can be prepared from 100 educts of its four different types.
Recently a particularly interesting one-pot synthesis of thiazole derivatives was accomplished from 1-amino-5-deoxy-5-thio-2,3,4-tri-O-isobutanoyl-[beta]-D-xylopyranose, an aldehyde of carboxylic acid and 2-isocyano-3-dimethylamino acrylic acid methylester as the educts [59, 60].
