摘要:通过两种方法合成了与叶酸和甲烷蝶呤有关的蝶啶衍生物.第一步合成是通过将5-甲基吡嗪-2,3-二腈(3)自由基取代成(n-酰基丙氨基)烷基,得到6-甲基-5-(n-酰基丙氨酸基)烷基吡嗪-2,3-(9),然后用甲胺取代2-甲腈,并进一步转化为1-甲基-2-氨基-6-(n-酰基丙氨酸)-烷基-7-甲基蝶啶-4(1 H)-亚胺11在胍的作用下.第二种方法是通过将5-甲基吡嗪-2,3-二腈(3)进行羟甲基化而得到5-羟基-甲基-6-甲基吡嗪-2,3-二腈(15),然后氧化羟甲基,N-苯基亚胺化,以及用甲胺取代2-甲腈,得到6-甲基-2-甲基-氨基--5-(n-苯基亚氨基)亚甲基吡嗪-3-甲腈(18).亚氨基的还原和胍的最终环化得到2-氨基-6-苯胺基甲基-1,7-二甲基蝶啶-4(1 H)-亚胺(20).

摘要:The present invention relates to a new type of inorganic coordination compound dyes having advanced technology optical, electronic and medical characteristics and relates to production of these dyes by means of new synthesis methods. The present invention relates to dyes which are metal (M: Li, Na, K, Mg, Ca, Sr, Ba, Ti, Zr, V, Cr, Mo, Mn, Re, Fe, Ru, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, B, Al, Ga, In, Si, Ge, Sn, Pb, Sb, Bi, Se, Te) complexes of aromatic macrocyclic compounds of the type Phtalocyanine (Pc), Naphtalocyanine (Nc), Porphyrazine (Pz), Porphyrin (Pr), sub-Phtalocyanine (subPc), sub-Naphtalocyanine (subNc), sub-Porphyrazine (subPz), sub-Porphyrine (subPr), and relates to the synthesis of these complexes and derivatives. The subject matter dyes can be used in solar cell photovoltaic (PV) panels, in OLEDS which are organic structured light emitting diodes, in polymers, in textile and in photodynamic therapy PDT applications. Moreover, industrial applications are possible which depend on strong fluorescence characteristics.
