We present a convenient synthesis of novel heteroaryl-fused 3-oxo-1,4-thiazepine-5-carboxamides and 5-oxo-1,4-thiazepine-3-carboxamides using a modification of four-component Ugi condensation. We demonstrate the usefulness and versatility of the developed approach for the synthesis of variously substituted compounds and discuss the scope and limitations of the chemistry involved.

In this work we have synthesized novel pharmaceutically relevant pyrrolo[1,2-b][2,5]benzodiazocines based entirely on the use of MCR between heterocyclic aldehyde-acid, amines, and isonitriles. The developed synthetic strategy provides an efficient one-step route to rare heterocyclic scaffold of paramount interest.

We present a convenient synthesis of novel pyrrole- and indole-fused 1-oxo-1,2,3,4-tetrahydropyrazine heterocyclic structures using a novel modification of four-component Ugi condensation. We demonstrate the usefulness and versatility of the developed approach for the synthesis of variously substituted compounds, and discuss the scope and limitations of the chemistry involved.

Anabasine served as a starting material for the synthesis of two series of novel, drug-like compounds. On the one hand, anabasine was subjected to a direct Chichibabin amination and elaborated into medicinally relevant, racemic 6-(piperidin-2-yl)imidazo[1,2-a]pyridines via the Groebke-Blackburn reaction. On the other hand, anabasine was used as an amine for the Ugi reaction to provide novel non-racemic anabasine-containing 2-[(2-pyridin-3-yl)piperidin-1-yl]acetamide peptidomimetics with high diastereoselectivity.
