Researchers from Zelinsky Institute developed a promising synthetic approach for the use in effective industrial processing of biomass

5-(Hydroxymethyl)furfural, which can be easily obtained from biomass (a renewable natural resource), has attracted a considerable attention as one of the most important polyfunctional platforms for the production of a variety of organic compounds. The use of 5-hydroxymethylfurfural and its derivatives to replace non-renewable resources for the production of biofuels, polymers, solvents, pharmaceuticals, and other useful molecules is a very important task.

One of the research direction of the Laboratory №30 ZIOC RAS is the development of new synthetic approaches to various classes of organic compounds based on 5-hydroxymethylfurfural and its derivatives. In their recent work, the researchers succeeded in finding of an efficient process of C-H functionalization of 2,5-diformylfuran at the low-reactive 3rd position. It should be also noted that the reaction proceeds without the use of directing groups in the starting substrates and ligands. The obtained compounds also demonstrated their high synthetic potential in the reactions of reduction and oxidation of carbonyl groups. Such a simple and effective synthetic approach is extremely promising for further application in the direction of efficient industrial processing of biomass.

Important events:

The European Academy of Sciences (Academia Europaea) was founded in 1988. It unites about four thousand globally acknowledged experts in mathematics, medicine, natural sciences, humanities, law, economy, and social and political sciences from many countries of Europe. Among its members are also European scientists who live in other regions of the world. Currently, it includes seventy two Nobel laureates and it should be highlighted that many of them were elected to the Academy before winning the Prize.
Prof Mario Pagliaro (Palermo Italy) gave two talks on June 8th and 9th.
Alexey Sukhorukov, N. D. Zelinsky Institute of Organic Chemistry, Moscow, Russia, and colleagues studied the selective reactions of in-situ generated metal azides on N,N-bis(oxy)enamines. By combining readily generated bis(oxy)enamine substrates with sodium azide and one of a variety of metal salts (including Mg, Cu, Zn, Co, and Ni), the researchers showed that the metal cation selectively alters the mechanism to favor the formation of specific organoazide products.
