Paragraph 0302-0304, (2016/10/08)
Polyamine compound (I) is new. Polyamine compound of formula A(NHCH 2CR1R2CH(R3)NR5R4) a(I) is new. A : primary amino, secondary amino, OH or mercapto (if a = 1) or amine group after removing primary aliphatic amino group; R1, R2 : monovalent 1-12C hydrocarbyl; or R1+R2 : divalent 4-12C hydrocarbyl (which is a part of 5-8C, preferably 6C carbocyclyl (optionally substituted)); R3 : H, (aryl)alkyl or alkoxycarbonyl; either R4 : 1-20C (cyclo)aliphatic or 1-20C aryl-aliphatic (both monovalent and optionally contains heteroatoms); and R5 : R4 or H; or R4+R5 : divalent 3-30C aliphatic group (which is a part of heterocyclyl with 5-8, preferably 6 ring atoms (optionally substituted and optionally contains further hetero atoms adjacent to N)); and a : 1-6. Independent claims are also included for: (1) preparing (I); (2) an adduct obtained by reacting (I) with at least one compound carrying at least one, preferably at least two reactive groups, preferably isocyanate-, isothiocyanate-, cyclocarbonate-, epoxide-, episulfide-, aziridine-, acryl-, methacryl-, 1-ethynyl carbonyl-, 1-propynyl carbonyl-, maleimide-, citraconimide-, vinyl-, isopropenyl- or allyl groups; (3) an isocyanate groups exhibiting composition comprising (a) at least one polyisocyanate, and (b) at least one hardener compound exhibiting at least two reactive groups, preferably primary amino-, secondary amino-, hydroxyl- or mercapto groups, where the polyisocyanate and/or the hardener compound comprises (I), a propanediamine derivative of formula (-NH-CH 2-C(R1)(R2)-CH(R3)-N(R4)-R5) (VIII) or at least two isocyanate groups exhibiting adduct; (4) a cured composition (i) obtained by reacting at least one polyisocyanate with at least one hardener compound of the above isocyanate groups exhibiting composition; (5) an epoxy resin composition comprising at least one epoxy resin, and (I); and (6) a cured composition (ii) obtained by reacting at least one epoxy resin with (I).
α-amino ketone synthesis from aldehydes and N-(α-dialkylaminoalkyl)benzotriazoles
Katritzky, Alan R.,Cheng, Dai,Musgrave, Richard P.
, p. 273 - 280 (2007/10/02)
Thiazolium salt-catalyzed reactions of aldehydes with morpholino-(alkylbenzotriazoles) allow the synthesis of a variety of α-amino ketones. The relationship between reaction conditions and selectivity is discussed.
