Heterocycles represent the largest diversity of organic compounds with signifcant chemical,
biomedical, and industrial applications. They exist in numerous natural products, dyes, and …

In this work, we provide the first generalized and critical analysis of data on the chemistry of
malononitrile dimer (2-aminopropene-1, 1, 3-tricarbonitrile)–a multifunctional reagent that is …

Abstract Novel pyridine-3-carbonitrile derivatives, denoted as (4a-j), were synthesized using
a convergent synthetic approach that involved a one-pot four-component reaction. This was …

The review summarizes and systematizes data on the methods for the preparation of
chromeno [2, 3-b] pyridines. Both multicomponent and pseudo-multicomponent synthetic …

A new series of bis (4 H‐chromene), bis (pyrano [3, 2‐c] chromene), and bis (pyrano [2, 3‐c]
pyrazole) each linked to the piperazine core via ether linkages was synthesized. The target …

Malononitrile dimer as a precursor reactant has been extensively applied in the diversity-
oriented synthesis of various heterocyclic motifs, bis-heterocyclic compounds, fused …

A concise and efficient approach to novel tetrahydroheptaazadicyclopenta [a, j] anthracene-
5, 7-diones, by the reaction of aldehydes with two moles of 7-amino-2-methyl-3 …

Abstract Novel 9-aminoimidazo [1, 2-a: 5, 4-b'] dipyridine-6, 8-dicarbonitriles were prepared
via the Michael addition reaction of readily accessible 2-(3H-imidazo [4, 5-b] pyrid-2-yl) …

Efficient procedures have been developed for the synthesis of novel series of bis (9, 10-
diaryl-hexahydroacridine-1, 8-diones) in which the two acridine moieties were linked to …

A synthesis of novel hybrid molecules containing thiazole or bis (thiazoles) each bearing
benzofuran and/or benzo [d] thiazole moieties by the reaction of the appropriate thioamide …
