S 98 Synthesis of pyrimido[1,2-a]indoles (minireview) / I. L. Nikonov, D. S. Kopchuk, G. V. Zyryanov, V. L. Rusinov // Chemistry of Heterocyclic Compounds. - 2021. - Vol. 57, № 10. - P993–995 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: This review considers methods for the synthesis of pyrimido[1,2-a]indoles and their ring-fused derivatives, covering publications from the last 10 years. Depending on the synthons used for assembling the target structure, three main approaches to the synthesis of pyrimido- [1,2-a]indoles can be distinguished: annulation of a pyrimidine ring to 2-aminoindoles, modification of other indole derivatives, and miscellaneous methods. |
