Α sustainable access to therapeutics is today imperative. More than ever, synthetic organic chemistry has embrace all aspects of green chemistry. The utility multicomponent reactions especially the Ugi reaction an established approach in drug discovery. Their diversity, speed and effectiveness, combined with their compatibility principles, render this type very often alternative multistep linear pathways active pharmaceutical ingredients. This critical review compares metrics, such as E-factor (environmental factor), AE (atom economy) PMI (process mass intensity) factors, industrial MCR syntheses six well-known commercial drugs.

Heteroannulations of cyanoacetamide-based MCR scaffolds utilizing formamide

Beilstein Journal of Organic Chemistry, Год журнала: 2025, Номер 21, С. 217 - 225

Опубликована: Янв. 24, 2025

C1 chemistry has a central role in the efficient utilization of single-carbon molecules, contributing significantly to sustainability, innovation and economic growth across various sectors. In this study, we present an rapid method for synthesizing variety heteroannulated pyrimidones using cyanoacetamide-based multicomponent reaction (MCR) chemistry. By utilizing specific MCR-based scaffolds as precursors employing abundant inexpensive formamide feedstock under neat conditions, were able efficiently access substituted thieno-, quinolino- indolopyrimidones without need column chromatography. Further, single-crystal X-ray structure was obtained, revealing certain geometrical features.
