Pseudo-Five-Component Condensation for the Diversity-Oriented Synthesis of Novel Indoles and Quinolines Containing Pseudo-Peptides (Tricarboxamides)
Authors
Abstract:
A novel series of indole and quinoline tricarboxamides were synthesized using simple and efficient one-pot pseudo-five-component reactions of 2-formylindole or 2-chloro-3-formyl quinolines, isocyanides, amines, and Meldrum’s acid as a CH-acid in CH2Cl2 at room temperature. This conversion has been achieved via the construction of new bonds including two C-C bonds, two C-N bonds, and one C=O bond. Remarkably, three peptide bonds were formed through a domino sequence including Knoevenagel reaction, [1+4] cycloaddition, deacetonation and also, aminolysis reaction. Particularly, a number of structurally remarkable and pharmacologically significant products were provided in excellent yields.

Ionic liquid 1,3-disulfonic acid imidazolium trifluoroacetate ([Dsim][TFA]) has been exploited as a highly efficient catalyst for the one-pot pseudo five-component reaction of phenylhydrazine (2 eq.) with ethyl acetoacetate (2 eq.) and arylaldehydes (1 eq.) in ethanol (reflux conditions). In this reaction, 4,4′‐(arylmethylene)‐bis(3‐methyl‐1‐phenyl‐1H‐ pyrazol‐5‐ol)s have been obtained in high ...

Design, synthesis, and metal binding of novel Pseudo- oligopeptides containing two phosphinic acid groups.
Phosphinic compounds have potential as amide-bond mimetics in the development of novel peptidomimetics, enzyme inhibitors, and metal-binding ligands. Novel pseudo-oligopeptides with two phosphinic acid groups embedded in the peptide backbone serving as amide-bond surrogates, Psi[P(O,OH)--CH(2)], were targeted. A series of linear and cyclic pseudo-oligopeptides with two phosphinic acid groups ar...
