    摘要:
    各种取代多环吡喃并[2,3- b ]吡喃通过4 H缩合合成-chromene-3-carbaldehydes 及其在乙酸中与杂环和碳环 1,3-二羰基化合物的缩合类似物。乙酸铵用作反应的绿色催化剂。该过程还涉及随后形成的 1-氧杂三烯中间体的 Knoevenagel 缩合和 6π-电环化。稠合吡啶作为氨共轭加成到 1-氧杂三烯中间体的产物被分离出来,同时使用碳环 1,3-二羰基化合物并增加反应时间,表明电环化阶段的可逆性。1-氧杂三烯- 2 H-吡喃平衡的吉布斯自由能和反应速率常数的计算值也证明了吡喃的不可逆性[2,3- b在使用杂环1,3-二羰基化合物的情况下形成吡喃。

    The present invention relates to the dyeing of keratin materials using two colorless dye precursors, at least one of which contains a disulfide/thiol unit, said precursors reacting together chemically to form the color in situ. The process according to the invention makes it possible in the context of certain variants to solve the problems caused by the color generated during the process, while at the same time not degrading the efficacy of the coloration, and especially of the lightening effect. The colorations obtained are moreover powerful, chromatic, sparingly selective, and fast with respect to external agents such as sunlight, perspiration and especially shampoo.
