  diversity-oriented synthesis of pyrido- and pyrimido-indoles from an acid-catalyzed three component (3C) reaction involving ethyl 2-amino-1H-indole-3-carboxylates, arylaldehydes, and terminal alkynes. In the presence of a Bronsted acid such as trifluoroacetic acid (TFA), the 3C reaction furnished a mixture of pyrido- and pyrimido-indoles, whereas when catalyzed by Yb(OTf)3 as a Lewis acid, pyrimidoindoles

  我们报告了从涉及 2-氨基-1H-吲哚-3-羧酸乙酯、芳醛和末端炔烃的酸催化三组分 (3C) 反应中合成吡啶和嘧啶并吲哚的多样性。在布朗斯台德酸如三氟乙酸 (TFA) 的存在下，3C 反应提供了吡啶和嘧啶并吲哚的混合物，而当由 Yb(OTf)3 作为路易斯酸催化时，得到嘧啶吲哚作为单一产物. 这些发现证明了通过改变酸催化剂来控制反应产物的能力。TFA 催化的 3C 反应的显着特征是炔丙胺形成后在一个锅中遵循两种不同的途径。
