In this letter, we report on our efforts to optimise the reaction conditions and to explore the scope and limitations of the preparation of 5-aminoindolizines starting from oxazolo[3,2-a]pyridinium salts and different amines to evaluate the utility for combinatorial library construction. Thus, we were able to reduce the amount of amine to 1.1 equiv by applying microwave heating, acetonitrile as solvent
                                    在这封信中,我们报告了我们为优化反应条件而进行的努力,并探讨了从
恶唑并[3,2- a ]
吡啶鎓盐和不同的
胺类化合物制备
5-氨基吲哚嗪的范围和局限性,以评估其用于组合文库的效用建造。因此,通过施加微波加热,
乙腈作为溶剂和
DMAP作为附加碱,我们能够将胺的量减少到1.1当量。此外,我们观察到只有空间需求有限的脂族仲胺才能提供所需的化合物。
