    摘要: The invention relates to β-alanine amides of general formula (I), wherein: R1 represents hydrogen or C¿1-6? alkyl that is optionally substituted by hydroxy, amino, carboxy, carbamoyl, methylmercapto, guanidino, optionally substituted aryl or heteroaryl, and; R?2¿ represents hydrogen or R?1 and R2¿, together, form a group of formula -(CH¿2?)n-, wherein n is 3 or 4. Said β-alanine amides are produced without using an amino protective group by reacting the corresponding amine with a cyanoacetic ester in order to form an acetamide and by effecting a subsequent catalytic hydrogenation. The method is suited, in particular, for producing carcinine (β-alanyl-histamine, R?1 ¿= imidazol-4-ylmethyl, R2 = H), a naturally occurring pseudo dipeptide, which is used as an active ingredient having an antioxidative effect in medicaments and cosmetics.

    摘要: The invention relates to prepolymer compositions on the basis of Novolac cyanates of the general formula (I), wherein n is a number of from 0 to 20 and the groups R are the same or different and represent hydrogen or methyl. The inventive compositions contain: 30 to 90 parts by weight of a prepolymer from Novolac cyanates (I) wherein R = hydrogen (Ia) and 10 to 70 parts by weight of Novolac cyanates (I) wherein R = methyl (Ib), and optionally highly dispersible silicon dioxides and/or particulate or fibrous fillers. The inventive compositions are solid at normal temperature and can be ground to flowable powders. They have an excellent stability when stored and are easy to process and especially suitable for use as the resin component in base materials for printed circuits and resin-bound abrasive products.
