Synthesis of Heteroarylogous 1H-Indole-3-carboxamidines via a Three-Component Interrupted Ugi Reaction
摘要:
A novel one-pot multicomponent synthesis of heteroarylogous 1H-indole-3-carboxamidines starting from readily available N-alkyl-N-(1H-indol-2-ylmethyl) amines, isocyanides, and carbonyl compounds is reported. The strategy exploits the ability of the indole nucleus to interrupt the classical Ugi reaction, by intercepting the nascent nitrilium ion.

rimethylammonium bromide (IS-Ph3P), could be used for the facile amidation of a wide range of carboxylicacids with amines in the presence of bromotrichloromethane to provide the corresponding amides in good yields. In the present reaction, the desired amides were obtained in good yields with high purity by simple extraction of the reaction mixture with diethyl ether or chloroform and subsequent removal

Newmonoamineoxidaseinhibitors were synthesized as indole analogues of a previously reported pyrrole series. Several compounds were potent MAO-A (12, 17, 19-22, 31, 36, and 37) or MAO-B (14, 20, 24, 38, 44, and 46) inhibitors, and had K(i) values in the nanomolar concentration range. In particular, 22 (K(i)=0.00092 microM, and SI=68,478) was exceptionally potent and selective as MAO-A inhibitor.
