Biginelli multicomponent reactions

open access: yes, 2015
Biginelli reaction is one of the most remarkable examples of MCRs discovered in 1893 and proof of its importance is the high number of articles reported in the last decade covering this field. This strategy allows the synthesis of important building blocks and versatile synthons such as 3,4-dihydropyrimidin-2-(1H)-one derivatives (DHPMs), which are ...

Multicomponent Reactions (MCRs) [PDF]

open access: yes, 2019
Multicomponent reactions (MCRs) involving three or more components have good pot, atom and step economy. There are dozens of well-known MCRs in literature. Selective examples of newly introduced MCRs, high–order MCRs, MCRs followed by post-condensation modifications, and consecutive MCRs are presented in this chapter.

Pyrrolidinodiones in Enol-Ugi, Enol-Passerini, and Anomalous Enol-Passerini Condensations

open access: yesProceedings, 2019
In continuation of our recent research on the development of novel multicomponent reactions with isocyanides, we have used, for the first time, enols as the acid components in Ugi- and Passerini-type reactions. Thus, electron-poor pyrrolidinodiones react

Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations

open access: yesAdvanced Functional Materials, EarlyView.
Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and
